    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 HEAVY HYDROCARBON STREAM IS CONVERTED IN A HIGHTEMPERATURE, HIGH PRESSURE FLUIDIZED COKER INTO A DISTILLAABLE, LOWER-BOILING HYDROCARBON PRODUCT OIL WHILE PRODUCING A COKE PRODUCT. THE COKE PRODUCT IS CONVERTED IN A HIGH-PRESSURE, HIGH-TEMPERATURE, PARTIAL COMBUSTION REACTOR INTO CARBON MONOXIDE, BY REACTION WITH STEAM AND A SMALL AMOUNT OF SUBSTANTIALLY PURE OXYGEN. THE CARBON MONOXIDE IS CONVERTED INTO CARBON DIOXDE IN A SHIFT REACTOR. THE HYDROGEN PRODUCED IN THE WATER-GAS REACTOR AND THE SHIFT REACTOR IS PREFERABLY USED TO HYDROCRACK THE LOWER-BOILING HYDRO-CARBON OIL PRODUCT FROM THE COKER, OR MAY BE USED FOR OTHER PURPOSES SUCH AS HYDROFINING ECT.

    Abstract: AN ADVANTAGEOUS HYDROGEN SUPPLY SYSTEM IS DISCLOSED FOR THE HYDROGENATION OF CERTAIN UNDESIRABLY AROMATIC PRODUCT FRACTIONS DERIVED FROM HYDRCRACKING SYSTEMS, WHEREBY ESSENTIALLY THE SAME EQUIPMENT AND POWER REQUIRED TO SUPPLY MAKEUP HYDROGEN TO THE HYDROCRACKING SYSTEM IS USED TO CIRCULATE HYDROGEN ONCE-THROUGH THE POST-HYDROGENATION SYSTEM, THEREBY ELIMINATING THE NEED FOR SEPARATE MAKEUP AND RECYCLE GAS COMPRESSORS FOR THE LATTER. DUE TO THE RELATIVELY HIGH CHEMICAL HYDROGEN CONSUMPTION IN THE HYDROCRACKING SYSTEM, AND THE RELATIVELY LOW FEED RATE AND MILD CONDITIONS IN THE HYDROGENATION SYSTEM, IT IS FOUND THAT THE MULTI-STAGE MAKEUP GAS COMPRESSOR REQUIRED FOR THE HYDROCRACKING SYSTEM CAN BE ADVANTAGEOUSLY UTILIZED TO MOVE THE MAKEUP HYDROGEN REQUIRED FOR THE HYDROCRACKER FIRST THROUGH THE HYDROGENATION SYSTEM, AND THAT SUCH MAKEUP HYDROGEN IS FORTUITOUSLY SUFFICIENT TO OPERATE THE HYDROGENATION SYSTEM IN ONCE-THROUGH FASHION, I.E. WITHOUT RECYCLE.

    Abstract: Unsaturated light hydrocarbons are produced by coking a heavy hydrocarbonaceous oil in a conventional fluid coking zone and subsequently heating the vaporous coker product to a higher temperature in a gas-solids separation zone, such as the coking reactor's cyclone separator, with hot solids derived from a coke gasification zone.

    Abstract: Clarified slurry oil feedstock is heated at temperatures above 340.degree. C. and preferably between 390.degree. C. and 410.degree. C. for periods exceeding a minimum of about 2 hours, under reflux conditions and in the absence of air, so as to maximize the polymerization of light ends in the formation of petroleum pitch. An increased yield of petroleum pitch is obtained from the clarified slurry oil feedstock.
