OLEFIN SKELETAL ISOMERIZATION PROCESS USING ZSM-35

摘要

A process is disclosed for the highly selective skeletal isomerization of linear olefin-containing organic feeds wherein linear olefins, e.g., n-butenes, are contacted with catalyst comprising ZSM-35, preferably microcrystalline ZSM-35 having its largest crystal dimension no greater than 0.5 micron, under isomerization conditions to produce iso-olefins of corresponding carbon number, e.g., isobutene.
