    摘要： A process is disclosed for the highly selective skeletal isomerization of linear olefin-containing organic feeds to iso-olefins at high levels of feed conversion wherein linear olefins, e.g., n-butenes, are contacted with catalyst comprising ZSM-35 under skeletal isomerization conditions which can include temperatures of 100 to 750.degree. C. The process uses a catalyst composition comprising ZSM-35, e.g., microcrystalline ZSM-35 having a crystal size whose largest dimension is no greater than 0.5 micron and whose ratio of its second largest dimension to said largest dimension ranges from 0.5 to 1. The process exhibits enhanced catalyst cycle life where the ZSM-35 is composited with a silica-containing matrix to provide a catalyst composite having a total pore volume greater than 0.6 cc/g or 300.sup.+ angstroms pore volume of greater than 0.1 cc/g.

    摘要： This invention provides a process for upgrading hydrocarbon feedstock comprising the steps of:(i) recovering a C.sub.4 -rich aliphatic stream from a catalytic cracking process;(ii contacting said C.sub.4 -rich aliphatic stream with an isomerization catalyst comprising a zeolite sorbing 30 to 55 mg n-hexane at 90.degree. C., 83 torr, and 15 to 40 mg 3-methylpentane at 90.degree. C., 90 torr, per g dry zeolite in the hydrogen form in a first reaction stage to selectively isomerize C.sub.4 n-olefins to C.sub.4 isoolefins; and(iii) contacting the product stream from said first reaction stage with a solid acid alkylation catalyst selected from the group consisting of MCM-36 and MCM-49, as described herein and zeolites having a Constraint Index of less than or equal to about 2, to produce isoparaffinic alkylate gasoline.
