    Abstract: A crude hydrocarbon oil or gas oil is cracked with a ''''used'''' cracking catalyst having a high metal content under conditions of severity to produce gasoline and lighter products to an optimum extent. Effluent is cooled to obtain a gasoline fraction with large amounts of H2 and light gases and a heavier product stream which is recycled to the cracking operation. Gasoline and higher components are dehydrosulfurized, using generated hydrogen for the purpose. Thus treated stream is cooled to obtain a liquid and a gas stream. A portion of the gas stream is used as a hydrogenrich gas for the catalytic hydrodesulfurization. Another portion is treated to remove H2S therefrom and thus treated gas and liquid obtained upon the cooling, after some preheat, are passed to a synthetic natural gas reactor, preferably after further treatment to produce a stream containing less than about one part per million of sulfur. The process is self-sustaining in hydrogen. Coke deposited on catalyst on regeneration yields sufficient heat to supply steam requirement for Synnat process.

    Abstract: CYCLOALKYLAROMATICS ARE PRODUCED FROM AROMATIC HYDROCARBONS IN THE PRESENCE OF HYDROGEN AND A RHODIUMACTIVE CLAY CATALYST. PREFERABLY THE CATALYST HAS NOT BEEN HEATED UNDER CALCINATION CONDITIONS PRIOR TO USE. IN A SPECIFIC EMBODIMENT, BENZENE IS CONVERTED TO CYCLOHEXYLBENZENE WITH GOOD SELECTIVITY OVER AN ACTIVE CLAY IMPREGNATED WITH RHODIUM TRICHLORIDE WHEREIN THE SOLVENT HAS BEEN REMOVED UNDER CONDITIONS WHICH DO NOT SUBJECT THE CATALYST COMPOSITION TO CALCINATION TEMPERATURE.
