Abstract: A process to convert an alkane, such as n-butane, to dehydrogenated and isomerized products comprises contacting such alkane under conversion conditions with an AMS-1B crystalline borosilicate catalyst composition containing an ion or molecule of a catalytically active element, such as a noble metal.

Abstract: A process for mild hydrocracking of hydrocarbon feeds comprising contacting the feed with hydrogen under mild hydrocracking conditions in the presence of a catalytic composition comprising an active metallic component comprising at least one metal having hydrogenation activity and at least one oxygenated phosphorus component, and a support component comprising at least one non-zeolitic, porous refractory inorganic oxide matrix component and at least one shape selective crystalline molecular sieve zeolite component.

Abstract: Hydrodenitrogenation of high nitrogen content hydrocarbon feeds comprises contacting the feed with hydrogen under hydrodenitrogenation conditions in the presence of a multiple catalyst system comprising an initial catalyst of apparent higher order reaction kinetics and lower rate constant for hydrodenitrogenation followed by at least one subsequent catalyst of apparent lower order reaction kinetics and higher rate constant for hydrodenitrogenation.

Abstract: Hydrocarbon feeds are treated to remove sulfur, nitrogen, oxygen, metals and/or other impurities by contact with treating gas comprising carbon monoxide and water under reaction conditions in the presence of catalysts having shift and hydrogenating activity as well as improved steam stability. The catalysts comprise (1) a metallic component having shift and hydrogenating activity, (2) a support component comprising activated alumina and (3) a steam stabilizing phosphorus component.

Abstract: A process which comprises fractionating a wide-boiling range naphtha feedstock into a low-boiling, light-naphtha fraction having an end or maximum boiling point within the range of about 190.degree. to about 200.degree. F. (88.degree. to about 104.degree. C.), and a high-boiling, heavy-naphtha fraction having an initial boiling point within a range of about 190.degree. to about 220.degree. F. (88.degree. to about 104.degree. C.), and contacting the light-naphtha fraction in an isomerization zone with added hydrogen and a catalyst comprising tantalum pentafluoride and hydrogen halide to produce effluent yielding naphthene components which are blended with the heavy-naphtha fraction. The resulting blended material can be processed by reforming to produce an aromatic-rich naphtha product and hydrogen.

Abstract: An isomerization process which comprises isomerizing a hydrocarbon component comprising at least one saturated C.sub.5 -C.sub.6 hydrocarbon in the presence of hydrogen and a catalyst comprising tantalum pentafluoride and hydrogen halide and in the presence of a hydrocarbon promoter comprising at least one member selected from the group consisting of C.sub.8 -C.sub.14 multiple-branched paraffins, wherein the total concentration of C.sub.8 -C.sub.14 multiple-branched paraffins, is in the range of about 1 to 50 parts by weight per each 100 parts by weight of said saturated C.sub.5 -C.sub.6 hydrocarbons.

Abstract: Heavy hydrocarbon streams containing asphaltenes are hydrocracked in a first hydrocracking zone and asphaltenes are removed from the liquid effluent to form a deasphaltened liquid feed to a second hydrocracking zone.

Abstract: Catalyst and process for octane upgrading of light naphtha feed by using a fluoroalkanesulfonic acid-antimony pentafluoride mixture as a conversion catalyst.
