    Abstract: A MODIFIED DUAL ADSORPTION AND ISOMERIZATION PROCESS EMPLOYING A COMBINATION OF AN ORTHO-XYLENE SEPARATION ZONE AND A FIRST ADSORPTION ZONE IN COMMUNICATION WITH A SECOND ADSORPTION ZONE AND AN ISOMERIZATION ZONE. THE PROCESS IS SUITABLE FOR THE SEPARATION OF VARIOUS C8 AROMATIC ISOMERS INTO INDIVIDUAL RELATIVELY PURE STREAMS CONTAINING THE INDIVIDUAL ISOMERS. THE ORTHO-XYLENE SEPARATION ZONE SEPARATES ORTHO-XYLENE FROM THE OTHER C8 AROMATIC ISOMERS CONTAINED IN THE FRESH FEED AND RECYCLE FEED AND PASSES THE REMAINING C8 AROMATIC ISOMERS TO A FIRST ADSORPTION ZONE. THE FIRST ADSORPTION ZONE THEN SEPARATES PARA-XYLENE AND ETHYLBENZENE FROM META-XYLENE AND PASSES THE PARA-XYLENE AND ETHYLBENZENE TO A SECOND ADSORPTION ZONE WHEREIN PARA-XYLENE AND ETHYLBENZENE ARE SEPARATED INTO RELATIVELY PURIFIED PARA-XYLENE AND ETHYLBENZENE STREAMS. THE REMAINING META-XYLENE SEPARATED FROM THE PARA-XYLENE IN THE FIRST ADSORPTION ZONE IS PASSED INTO AN ISOMERIZATION ZONE TO EFFECT THE PRODUCTION OF ADDITIONAL C5 AROMATIC ISOMERS WHICH ARE RECYCLED TO AND SEQUENTIALLY SEPARATED BY THE ORTHO-XYLENE SEPARATION ZONE AND THE FIRST AND SECOND ADSORPTION ZONES, ALLOWING INCREASED YIELDS OF SOME OF THE C8 AROMATICS BASED ON FRESH FEED TO THE ORTHO-XYLENE ZONE. THE MODIFICATION BASICALLY COMPRISES SEPARATING AND REMOVING ORTHO-XYLENE FROM

    THE FEED TO THE ISOMERIZATION ZONE THUS ALLOWING THE PRODUCTION OF ADDITIONAL ORTHO-XYLENE IN SAID ZONE AND THEREBY RESULTING IN A HIGHER OVERALL YIELD OF ORTHO-XYLENE BASED ON FRESH FEED THAN THAT RESULTING IF ORTHO-XYLENE WERE NOT SEPARATED AND REMOVED.

    Abstract: A PROCESS FOR CONVERTING HYDROCARBONACEOUS BLACK OILS INTO LOWER-BOILING, NORMALLY LIQUID HYDROCARBON PRODUCTS. THE PROCESS INVOLVES THE INTERGRATION OF HYDROGENATIVE CRACKING AND FIXED-BED CATALYTIC DESULFURIZATION, AND IS ESPECIALLY APPLICABLE TO THOSE HYDROCARBON CHARGE STOCKS CONTAINING LESS THAN 150 P.P.M. OF METALLIC CONTAMINANTS, AND MORE THAN ABOUT 10.0% BY VOLUME NON-DISTILLABLES. THE CHARGE STOCK IS INITIALLY SUBJECTED TO A FIXED-BED CATALYTIC HYDROGENATION AND DESULFURIZATION REACTION ZONE. FOLLOWING SEPARATION OF THE REACTION ZONE EFFLUENT, A HIGHBOILING CONCENTRATE IS THERMALLY CRACKED IN A HYDROVISBREAKING OPERATION.

    Abstract: A catalytic slurry process for effecting the conversion of a hydrocarbonaceous charge stock containing asphaltenes and metallic contaminants. The slurry constitutes charge stock, hydrogen, from about 1.0 to about 25.0 percent by weight of finely divided catalyst particles and, in a preferred embodiment, a portion of the previously produced product effluent. Preferred catalysts are the unsupported sulfides of the metals from Groups V-B, VI-B and VIII. Prior to an initial separation, hydrogen sulfide is commingled with the product effluent in order to convert the metals contained therein to the sulfides thereof.

    Abstract: A HEAVY HYDROCARBON FEEDSTOCK IS CONVERTED INTO MORE VALUABLE HYDROCARBON PRODUCT BY A COMBINATION EXTRACTION AND HYDROREFINING PROCESS WHICH INCLUDES THE CONTACTING OF THE FEEDSTOCK IN A LIQUID-LIQUID CONTACTING ZONE WITH A LIGHT HYDROCARBON SOLVENT UNDER CONITIONS SUFFICIENT TO PRODUCE A LOW DENSITY LIQUID PHASE COMPRISING SOLVENT AND A LOW BOILING FRACTION OF THE FEEDSTOCK, AND A HIGH DENSITY LIQUID PHASE COMPRISING SOLVENT AND A HIGH BOILING FRACTION OF THE FEEDSTOCK. THE LOW DENSITY PHASE IS PASSED TO A HYDROREFINING REACTION ZONE AND THE RESULTING EFFLUENT CONTAINS HYDROREFINED HYDROCARBON AND SOLVENT. THE EFFLUENT AND THE HIGH DENSITY PHASE ARE PASSED TO A FRACTIONATION ZONE WHEREIN THE HIGH BOILING FRACTION OF

    THE FEEDSTOCK IS RECOVERED, HYDROREFINED PRODUCT IS RECOVERED, AND LIGHT HYDROCARBON SOLVENT IS RECOVERED FOR RECYCLE TO THE CONTACTING ZONE. THE LIGHT HYDROCARBON SOL VENT CONTAINS HYDROCARBONS HAVING FROM THREE TO TEN CARBON ATOMS PER MOLECULE, AND PREFERABLY FROM FIVE TO EIGHT CARBON ATOMS PER MOLECULE. THE PROCESS HAS PARTICULAR APPLICATION TO HYDROTREATING AND HYDROCRACKING HEAVY FEEDSTOCKS CONTAINING A SIGNIFICANT QUANTITY OF ASPHALTIC MATERIALS, ORGANO-METALLIC COMPLEXES, SULFUR COMPOUNDS, AND NITROGEN COMPOUNDS, WHEREIN AT LEAST ABOUT 10% BY VOLUME OF THE FEEDSTOCK BOILS AT A TEMPERATURE IN EXCESS OF ABOUT 1050*F.
