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.
