Title of Invention

CONTINUOUS PROCESS FOR THE ALKYLATION OF HYDROCARBONS

Abstract The present invention relates to a continuous alkylation process wherein an alkylatable compound is reacted with an alkylation agent in the presence of a solid acid alkylation catalyst to form an alkylate and wherein the catalyst is regenerated, said process being performed in an apparatus comprising a series of at least two catalyst-containing reactors (4A, 5A) in a zone A and a series of at least two catalyst- containing reactors (4B, 5B) in a zone B, in which process (a) the zone A reactors and the zone B reactors cycle back and forth per zone between the alkylation mode and the mild regeneration mode, (b) the alkylation mode comprises introducing an alkylation agent into a first reactor (4A,4B) of the zone through which the alkylatable compound passes, reacting a portion of the alkylatable compound with at least a portion of the alkylation agent to produce an alkylate-containing product stream, and performing this operation at least once more in a downstream reactor (SA,5B) in the same zone employing, instead of said alkylate compound, a stream comprising said alkylate- containing product stream which mayor may not have been subjected to a prior intermittent separation during which a portion of the alkylate has been removed, to produce an alkylation mode alkylate-containing effluent, (c) the mild regeneration, , mode comprises contacting the solid acid alkylation catalyst with hydrogen in each of the at least two reactors of the zone, (d) alkylate is recovered,
