Title of Invention	A PROCESS FOR HYDRODENITIRIFICATION OF HYDROCARBONS
Abstract	A process for hydrodenritification of hydrocarbons comprising contacting the hydrocarbons with hydrogen in the presence of a layered catalyst composition comprising a first layer of a catalyst constituting upto 70 vol % based on the total volume of the catalyst which comprises a nlckel-molybdenum- phosphorus/alumina catalyst or a cobalt-molybdenum-phosphorus/ alumina catalyst having a molybdenum content greater than 14 ~ by weight of the first layer catalyst and having an average pore size of at least 60A and a second layer of a catalyst placed downstream from the said first layer and comprises a nlckel-tungsten/silica-alumina-zeolite or a nickel-molybdenum- silica-alumina-zeolite catalyst, wherein the zeolite component comprises at least 2 % by weight of the second layer catalyst.
