Conversion of catalytic gas oil to lower boiling hydrocarbons

Claim 1

METHOD OF CONVERTING AN AROMATIC CATALYTIC GS OIL STOCK INTO LOWER BOILING SATURATED HYDROCARBONS WHICH COMPRISES HYDROGENATING SAID STOCK TO FORM A SUBSTANTIALLY SATURATED GAS OIL CONTAINING NAPTHENES CORRESPONDING TO THE AROMATICS IN THE CATALYTIC GAS OIL STOCK, REACTING SAID SATURATED GAS OIL IN THE ABSENCE OF ADDED LOWER MOLECULAR WEIGHT NAPHTHENE HYDROCARBON AT A TEMPERATURE OF 0-100*C. IN THE PRESENCE OF A CATALYST SELECTED FROM THE GROUP CONSISTING OF AICI3-HCI CATALYST AND AIBR3-HBR CATALYST WHILE IN CONTACT WITH HYDROGEN UNDER A PARTIAL PRESSURE OF 25-1000 P.S.I., CONTINUING THE REACTION FOR A TIME SUFFICIENT TO CONVERT AT LEAST A MAJOR PORTION OF THE SATURATED GAS OIL INTO LOWER BOILING HYDROCARBONS, AND RECOVERING FROM THE REACTION MIXTURE HYDROCARBONS SO OBTAINED MAINLY COMPRISING C4-C7 PARAFFINS, C6C11 MONOCYCLE NAPHTHENES AND C10-C13 DECAHYDRONAPHTHALENES.
