BACKGROUND OF THE INVENTION
The present invention relates generally to liquid fuel compositions such as those
which may be used in internal combustion engines
Environmental pollution from exhaust gases from engines, such as those used in
automobiles, is a widespread problem. Various liquid fuel compositions have been tried
in an effort to reduce such pollution. For example, it has been tried to form fuels from
mixtures of naphtha or gasoline with methanol or other alcohols. Such fuels can greatly
reduce the concentration of carbon monoxide (CO) and hydrocarbons in the exhaust
gases. They can also replace conventional gasoline fuel.
When selecting a fuel composition, a number of factors must be considered. The
fuel must be readily converted into energy by the engine In an internal combustion
engine, this means the fuel must have some volatility and must not be too viscous. The
fuel must have good performance, that is, it must combust readily to give good
acceleration to a vehicle. Preferably it should be stable, so that it does not separate on
standing and does not chemically react with engine components during storage. It should
be non-corrosive so that it does not damage the engine supply lines or storage vessels.
The combustion products which will appear in the exhaust gases should be as low as
possible in substances which are toxic or harmful to health or environment.
Although conventional gasoline does meet some of the above objectives, it is not
a renewable resource. Thus it would also be desirable to find a fuel composition which
was derived at least partly, from a renewable resource.
Although prior art fuels, which contain naphtha or gasoline mixed with methanol,
ethanol or other alcohols do have a small effect in reducing the concentrations of carbon
monoxide (CO) and hydrocarbons in the exhaust gases from automobiles, they have
other problems. Since they contain unstabilized alcohols and ethers, they can cause
problems such as swollen rubber gaskets, decomposition of rubber, engine parts
corrosion and wear, reduced performance affecting fuel consumption and driveability

index, oxidation stability and increased NOx values to name a few. Such fuels are also
known to break down and degenerate during storage or at high temperature and may
cause a build-up of gum residue on engine parts. In addition, these fuels are usually
unable to operate once water is added to them, as the water does not properly dissolve in
the fuel and tends to separate back out of the mixture after only a short time which in
turn causes engine stalling and poor performance.
The present invention seeks to provide an emission reducing liquid fuel, which
avoids or reduces some of the above problems and is therefore better for the
environment. The present invention seeks to provide an improved emission reducing
liquid fuel capable of efficiency and an output similar 1o or better than that of
conventional gasoline, without any need to modify existing internal combustion gasoline
engines. The invention also seeks to reduce the concentrations of carbon monoxide
(CO), carbon dioxide (CO2), sulphur dioxide (SO2), nitrogen oxides (NOx), particulate
matter (PM), volatile organic compounds (VOC) and total hydrocarbons (THC) in
exhaust gases as compared to conventional gasoline.
SUMMARY OF THE INVENTION
It has now been found that fuel compositions which contain at least some water
can outperform other fuel compositions, at least in some respects. The fuel composition
of the invention not only can include water without separation of the components but can
also improve the power of the fuel. Further, NOx and other emissions can be reduced,
the composition can have improved oxidation stability and can reduce, by way of pH
balancing, corrosion and wear. It further enables a way of using, in a new way, biomass
products which might not otherwise be useful.
According to one aspect of the present invention there is provided a liquid fuel
composition comprising: 10-80 vol% of a first component comprising at least two
aliphatic organic non-hydrocarbon compounds; 20-65 vol% of a second component
comprising at least one hydrocarbon and having an aromatic content of less than 15
vol% of the total of the second component; 1-35 vol% of a third component, which
comprises an oxygenate; 0.01 to 20 vol% water, wherein at least one compound in the

fuel composition is miscible with both water and hydrocarbons to provide a single phase
composition.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The first component comprises at least two aliphatic non-hydrocarbon organic
compounds. Preferably these are volatile compounds. Suitable compounds include
aliphatic monohydric alcohols, ketones, aldehydes and esters (such as acetates)
preferably having up to about 13 carbon atoms. Compounds which form undersirable
combustion products (for example, aldehydes which may form formaldehyde) are less
preferred. In a conventional combustion engine, performance may be a combination of
performances in a range. Thus, for example, a compound of lower boiling point may
make a certain contribution to the overall performance of the fuel, but may leave another
aspect of the performance lacking. The lacking aspect may be compensated or fulfilled
by a compound of a different, perhaps higher, boiling point. Thus it is preferred to have
several compounds in this component in the composition to represent a full range of
values.
The compositions can contain from 10 to 80 vol%, preferably from 30 to 50
vol%, more preferably from 35 to 45 vol% of the first component. However, the
quantity used will depend on many factors including the nature of the other ingredients,
availability and cost.
Although in some cases as little as 10 vol% of the first component may be used,
more preferably the fuel composition has at least 35 vol% of the first component.
Compounds suitable for the first component may be derived from any source,
such as petroleum, natural gas, coal or bio feedstock. One suitable source of compounds
for the first component is recycled solvents.
Use of the first component can thus reduce corrosion and undesirable products
such as CO, CO2, HxCy, SOx, NOx, THC, VOC, aromatics etc. contained in the
exhaust gases of automobiles.
It is preferable that at least one compound of the first component is an aliphatic
monohydric alcohol which is a non-straight chain alcohol.

The use of a non-straight chain or branched aliphatic alcohol can contribute to
obtaining a higher octane value and also can facilitate blending of the components
without separation.
Preferred compounds for use in the first component include ethyl alcohol, propyl
alcohol, butyl alcohol, octyl alcohol, butanone, methyl isobutyl ketone and ethyl acetate.
Preferred branched aliphatic alcohols include isopropyl alcohol (IPA) and
isobutyl alcohol (IBA).
Although many different compounds may be used as compounds for the first
component, some, such as methyl alcohol (which tends to be quite corrosive) are less
preferred or are preferably avoided or only used in lesser quantities.
The compositions need at least one compound which is mutually miscible with
both water and hydrocarbons to ensure that, after blending, the components combine as a
single phase. Compounds suitable for use as the first component, for example alcohols,
especially higher alcohols such as decanol, will often provide such mutual miscibility
and can thus function as mutually miscible compounds.
The second component is the hydrocarbon component. It is preferred that this
component is low in aromatic content, (i.e., compounds such as benzene, toluene and
xylene) at least less than 15 vol%, preferably less than 10 vol%. Aromatic hydrocarbons
tend to be imperfectly combusted. Thus, by reducing the aromatic content the COx and
hydrocarbon content in the exhaust can be reduced, as well as reducing the exhaust
aromatic content. Further, it is believed that the aromatic content contributes to negative
properties of a fuel composition, such as the corrosiveness, and thus a lower aromatic
content is preferred.
The hydrocarbons may be saturated or unsaturated and may be derived from any
source such as petroleum, natural gas, coal or bio-feedstock. Thus they may be mixtures
of various hydrocarbons, the hydrocarbons are preferably straight chain. Light naphthas
are suitable. Some types of gasoline would also be suitable.
The compositions can contain from 20 to 65 vol%, preferably from 40 to 55
vol%, more preferably from 45 to 50 vol%, of the hydrocarbon component.

The specifications of an example of a suitable light naphtha for the second
component are shown below:

Further, straight-chain saturated or unsaturated hydrocarbons whose number of
carbon atoms is 9 or less may be used in place of all or a part of the low aromatic
naphtha for the second component.
The third component comprises at least one oxygenate. Oxygenates are usually
compounds which contain oxygen and which can provide a source of oxygen during
combustion to assist in the complete combustion of the carbon content of the other
compounds in the fuel composition and can reduce the content of carbon monoxide in the
exhaust.
The compositions can contain from 1 to 35% of the third component, preferably
from 5 to 20 vol%, more preferably from 8 to 15 vol%.
Suitable compounds are compounds such as ethers which generally have at least
two hydrocarbon groups which each have seven, preferably six, or less carbon atoms in
the hydrocarbon chain. Preferred ethers include methylcyclopentadienyl manganese

tricarbonyl (MMT), methyl tertiary butyl ether (MTBE), tertiary amyl methyl ether
(TAME) ethyl tertiary-butyl ether (ETBE) and dibutyl ether or a similar component. Iso
octane is also sometimes used as an oxygenate.
In this way, the octane value of the resulting fuel can be improved by a small
blended amount without compromising the integrity of the fuel, so the price of the fuel
can be kept low level and lubricity can be maintained.
The compositions contain at least some water, in particular from 0.01 vol% to 20
vol%. It has been found not only that it is possible to use water in such fuel
compositions, but also that the water can contribute to the beneficial properties of the
compositions such as by reducing NOx, CO or particulate content in the exhaust.
Preferably the compositions contain at least 0.05 vol%, more preferably at least 0.75
vol% and particularly at least 1 vol%. It has also been found that the water may contain
various dissolved or suspended substances without disabling the fuel and sometimes even
enhancing the effects of the fuel.
Although in some cases there may be as much as 20 vol% of water in the
compositions, it is preferred that there is less than 10 vol% and more preferably, less
than 5 vol% of water.
The water may be derived from most sources. For example the water may be tap
water, distilled water, spring or mineral water or distilled sea water. Also the water may
include compounds derived from biomass or biological materials such as grass clippings,
leaves, fruits and plants. Of course, some compounds, such as sugars, would be
detrimental to the compositions and should be avoided. With regard to sugars, it is still
possible to use aqueous solutions derived from sugar-containing material, such as fruit
juice, provided the sugars are removed, such as by fermentation. Although some trials
may be needed to determine limits and suitability of such additional materials, an
advantage of the fuel compositions is that they do permit the use of such renewable
biological materials. Thus the water may contain various water soluble compounds such
as chlorophylls, lipids, proteins, phytols, carotenes, quercetin, acids (such as citric acid)
and alkaline compounds. The water may also contain urea, thus if salt and mineral
content is appropriately reduced or removed, urine may be used as water component.

Compounds derived from biomass may be obtained, for example, by grinding
into small pieces or mulching products such as grass clippings, leaves or fruits. Water is
added together with compounds which may accelerate the breakdown of the products and
the extraction of soluble compounds, the resulting mixture is pressed and filtered to
obtain an aqueous solution of compounds derived from biomass.
A variety of compounds may be present as additives in fuel compositions
according to the invention. Thus it is frequently desirable, and sometimes necessary to
adjust the properties by providing one or more additives. Types of additive which may
be used include: compounds which improve the miscibility of the water in the
composition (water bonding agents) or help stabilize the compositions against oxidation;
compounds which help adjust the pH of the compositions (pH balancing agents)
preferably to bring the composition to a non-corrosive neutral pH value; compounds
which reduce corrosiveness or provide lubricity (lubricants) by inhibiting reaction with
or adherence to engine or storage components; compounds which help stabilize the
compositions for long term storage (stabilizing agents) by reducing gum or residue build-
up in carburettors and other engine parts or storage components or by prolonging the
storage life of the fuel; and compounds which reduce the flash point of the compositions
and thus improve their safety. Compounds useful as additives which function in one or
more of the above capacities include: decanol, dodecanol, tetradecanol, octyl alcohol,
cyclohexane, pentane, methyl cyclohexane or similar material and micro lubricating
synthetic and petroleum distillates. Petroleum distillates, also called synthetic
(lubricating) distillates and petroleum lubricating distillates, provide a readily available
source of compounds which can function in a lubricant or corrosion reducing capacity,
for example, Octel Starreon markets a mixture of suitable synthetic lubricant distillates
under the Trade name DC11.
It is preferred that the volume percentage of the first component is 40% or more
than that of the second component. In particular, it is preferred that the volume
percentage of the first component is 50% or more that of the second component.
There may be overlap between the components. That is, for example, compounds
such as (lower) alcohols or esters which are suitable as the aliphatic non-hydrocarbon

compounds of the first component may serve as an oxygenate which is the third
component. Water also may sometimes serve as at least a part of the oxygenate
component.
Further, a non-straight chain monohydric (primary) alcohol, ketone or acetate is
preferably employed as at least one compound of the first component because the
polarity may be lower than that of a straight-chain alcohol and thus blending with
hydrocarbon components, ethers and esters may be improved.
Further, with regard to volatility and cost it is preferable to use, as the ether, an
ether having two chain hydrocarbon groups whose number of carbon atoms is 6 or less.
Since there is a range of suitable compounds for the components, the choice of
particular compounds may be based on cost or availability.
Bearing in mind that compounds containing nitrogen or sulphur as heteroatoms
will tend to contribute to the concentration of NOx and SOx in the exhaust gases, it is
preferred to use less of such compounds, or avoid using them.
To prepare the compositions, the various components, and any desired additives,
are mixed together followed by stirring, agitation or any other mechanical motion
needed to blend the composition into a single phase. It is important that the compositions
are stable and remain in a single phase. If any phase separation occurs it may render the
composition unsuitable as a fuel. The order of mixing is generally not critical, however
it will be understood that it is preferable to first mix components of similar polarity or
which are mutually soluble. On the one hand, any ethers, esters, ketones and alcohols
may be sequentially added to the hydrocarbon component such as low aromatic naphtha
which has low polarity. On the other hand, any ethers, esters, ketones and the low
aromatic naphtha may be sequentially added to any alcohol. Also the water component is
preferably added first to an alcohol component. Also it is preferred to first prepare a test
mix and establish the pH value of the solution, so that if any pH adjusting agent is
needed to neutralize the pH, the quantity needed can be established. If the mixture is too
acid it may be desirable to add an appropriate amount of an alkaline pH adjusting agent
and if the mixture is too alkaline it may be desirable to add an appropriate amount of an
acidic pH adjusting agent.

As a first step in formulation, it is preferred to do a sample mix of the aliphatic
monohydric alcohols, saturated and unsaturated hydrocarbons and ether or ester to
determine the pH value. This may vary from acidic to alkaline. With this determined,
one can then adjust the water and other ingredients to appropriate levels to ensure that
the final formulation has approximately a neutral pH. Use of watery fluids derived from
plant based material can provide added energy value and varies from alkaline to acidic.
The respective blended primary fuels can thus be effectively mixed without being
separated from each other.

emissions test) and Environment Canada Emissions Tests. Environment Canada tests
were conducted on a 1989 Crown Victoria and al990 Plymouth Acclaim for both
highway and city driving test cycles.
In the following tables: ODC stands for Ontario Drive Clean which is an
emissions test procedure of the Ontario provincial government of Canada; ECET stands
for Environment Canada Emissions Test which is an emissions test procedure of the
Environment Department of the Federal Government of Canada; where a number of a
blend is referred to, such as "Blend 1", it is intended to refer to a blend of the same
number as defined above in the Examples 1 to 10; "City" means the test was intended to
reflect city driving conditions and "Hiway" means the test was intended to reflect
highway driving conditions; "gas" or "gasoline" means that the composition tested was
a conventional gasoline used for comparative purposes, since a fuel was sometimes used
in engines of different make, the results in the table are sometimes different for the same
blend of fuel, but the comparison with regular gasoline shown in the table, illustrates the
improvements achievable by compositions of the invention.
