Abstract: A PROCESS FOR HYDROGENATING BENZENE IN THE VAPOR PHASE WITH MOLECULAR HYDROGEN IN A REACTION ZNE IN THE PRESENCE OF DILUENT CYCLOHEXANE VAPOR AND A HYDROGENATION CATALYST WHEREIN A PORTION OF THE HEAT OF REACTION IS ABSORBED FROM THE REACTION ZONE BY INDIRECT HEAT TRANSFER MEANS INTO A CIRCULATING LIQUID STREAM COMPRISING CYCLOHEXANE AND BENZENE AND WHEREIN SUCH HEATED CIRCULATING LIQUID STREAM IS CONTACTED WITH A MOLECULAR HYDROGEN CONTAINING GAS TO FORM A VAPORIZED REACTION CHARGE MIXTURE COMPRISING BENZENE, HYDROGEN AND DILUENT CYCLOHEXANE. REACTION ZONE TEMPERATURES ARE MAINTAINED WITHIN A DESIRABLE OPERATING RANGE BY ABSORBING HEAT FROM THE REACTION ZONE INTO THE CIRCULATING LIQUID STREAM AND SUCH ABSORBED HEAT IS SUBSEQUENTIALLY UTILIZED TO VAPORIZE THE BENZENE AND CYCLOHEXANE COMPONENTS OF THE REACTION CHARGE MIXTURE AND TO PREHEAT THE REACTION CHARGE MIXTURE TO THE DESIRED REACTION INLET TEMPERATURE.

Abstract: A process for the production of high octane motor gasoline stocks by catalytic cracking in which a distillate charge stock boiling above about 400* F is subjected to catalytic cracking in a catalytic cracking unit at limited per pass conversion not exceeding 80 volume percent of the charge stock, 430* F + gas oil product of the catalytic cracking operation is subjected to hydrogen treatment to lower its polycyclic aromatic content, as indicated by ultraviolet absorption to a concentration approximating that of the fresh charge stock to the catalytic cracking unit, and liquid effluent of the hydrogen treatment step is passed to the catalytic cracking unit as part of the feed thereto, producing exceptionally high yields of high octane naphtha suitable as motor gasoline blending stock.

Abstract: A RESIDUE-CONTAINING PETROLEUM FRACTION, 50 PERCENT BOILING ABOVE 1,000*F., IS HYDROCRACKED AND THEN HYDRODESULFURIZED. DURING THE ONSTREAM PERIOD, THE CONVERSION LEVEL OF MATERIAL BOILING ABOVE 1,000*F. IS MAINTAINED SUBSTANTIALLY CONSTANT WHILE THE SULFUR CONTENT OF THE HYDROCRACKED EFFLUENT INCREASES. THE SULFUR CONTENT OF A PRODUCT FRACTTION IS MAINTAINED SUBSTANTIALLY CONSTANT BY GRADUALLY INCREASING THE HYDROSULFURIZATION TEMPERATURE. THE EFFLUENT FROM THE HYDROCRACKING REACTTION IS COOLED BY ADDING AN AROMATIC-RICH FRACTION AND THE COOLED MIXTURE IS PASSED TO THE DESULFURIZATION REACTION.

Abstract: A residue-containing petroleum fraction, 50 percent boiling above 1,000* F, is hydrocracked and then hydrodesulfurized. During the onstream period, the conversion level of material boiling above 1,000* F is maintained substantially constant while the sulfur content of the hydrocracked effluent increases. The sulphur content of a product fraction is maintained substantially constant by gradually increasing the hydrodesulfurization temperature. The effluent from the hydrocracking reaction is cooled by adding an aromatic-rich fraction and the cooled mixture is passed to the desulfurization reaction.

Abstract: Low pour fuel oils are obtained by first converting waxy pour residua into the corresponding viscous pour residua by deep vacuum fractionation, with or without auxiliary visbreaking or thermal or catalytic cracking, and then blending with sufficient low pour cutter stock to produce fuel oils having commercially acceptable viscosities and pour points.
