Abstract: The present invention provides a process for alkylating an isoparaffin with an olefin comprising contacting an isoparaffin having from 4 to 8 carbon atoms with an olefin having from 2 to 12 carbon atoms in an alkylation reaction zone at temperature from about -20.degree. C. to about 200.degree. C. in the presence of a Bronsted acid and an inorganic, porous crystalline phase material having, after calcination, a d-spacing greater than about 18 Angstrom Units and having a benzene adsorption capacity of greater than 15 grams benzene per 100 grams of said material at 50 torr and 25.degree. C., wherein the molar ratio of said isoparaffin to said olefin is from about 1:1 to about 250:1 to evolve a product stream containing C.sub.5 + alkylate.

Abstract: A Pt/Ba/USY catalyst prepared with a high SiO.sub.2 /Al.sub.2 O.sub.3 ratio USY gives improved aromatics selectivity compared to other Pt/USY containing catalysts. The improved selectivity is a result of the method of catalyst preparation which includes incorporation of a Group IIA metal after platinum incorporation.

Abstract: The invention provides a catalyst complex for promoting alkylation of an isoparaffin with an olefin, said catalyst complex comprising the reaction product of Lewis acid and at least one fluorophosphoric acid; and, additionally, excess Lewis acid in concentration of from about 10 ppm (weight) to about 10000 ppm by weight of the total isoparaffin and olefin feed. The invention further provides a process for the alkylation of an isoparaffin with an olefin by contacting a mixture of isoparaffin and olefin with the catalyst complex of the invention.

Abstract: The present invention provides a Lewis acid-catalyzed isoparaffin/olefin alkylation process in which acid consumption and energy costs are decreased by employing an acid sorption stage to separate the Lewis acid catalyst from the alkylate product stream, or from a selected fraction of the alkylate product stream, and desorbing the Lewis acid from the sorption stage with an isoparaffin-containing alkylation process feedstream.

Abstract: A low acidity Group VIII metal-containing zeolite MCM-22 catalyst, said zeolite exhibiting an Alpha value of not greater than about 150, is provided for conversion of aliphatic C.sub.2 to C.sub.12 hydrocarbon(s) to olefin(s) and/or aromatic(s).

Abstract: The invention is a catalytic process for isomerizing an olefin under catalytic isomerization conditions, in the presence of an olefin isomerization catalyst comprising MCM-22. The light olefins are linear and/or branched olefins containing greater than three carbon atoms. The olefins can be contained in a fraction having a boiling range of from C.sub.5 + to 390.degree. F.

Abstract: The process relates to converting normal paraffins and/or mono-methyl branched paraffins, which are generally of low octane value, to more highly branched isoparaffins which are generally superior to normal paraffins in octane.

Abstract: A process for producing 2,6-dimethylnaphthalene by alkylation of an alkylaromatic, e.g. toluene, with a C.sub.5 olefin alkylating agent, e.g. 1-pentene, in the presence of a suitable alkylation catalyst, and dehydrocyclization of the resulting alkylate with a dehydrocyclization catalyst to generate a dimethylnaphthalene product rich in the 2,6-isomer. Additional process steps can include isomerization of the product and further alkylation.

Abstract: Alkylated polycycloparaffinic compounds useful as lubricating stocks are prepared by alkylating a polycycloparaffinic compound with an alkylating agent under alkylation reaction conditions in the presence of a zeolite catalyst. Useful zeolites include zeolite Beta as well as zeolites having a Constraint Index of from about 1 to about 10, such as ZSM-5 and MCM-22. In a preferred embodiment, the polycycloparaffin comprises adamantane and the alkylating agent is a C.sub.14 alpha-olefin.

Abstract: Aliphatic C.sub.2 to C.sub.12 hydrocarbon(s) are converted to olefin(s) and/or aromatic(s) in the presence of a low acidity Group VIII metal-containing zeolite MCM-22 catalyst, said zeolite exhibiting an Alpha value of not greater than about 150.
