    摘要: Normal olefins such as n-butenes and normal alkanes such as n-butane can be coverted to branched olefin species such as isobutylene by skeletal dehydroisomerization over catalysts preferably containing metals selected from Groups IB, IIB, IIIB, IVB, VB, VIB, VIIB, VIII and the rear earth elements which are deposited upon borosilicate zeolites having pore sizes of at least about 5 Angstroms and containing boron in the framework structure thereof. The borosilicates have sufficient acidity to catalyze the skeletal isomerization of both normal alkanes and normal olefins. The catalysts can be used to produce isoolefins for reaction with alcohols in integrated processes to produce alkyl tertiary alkyl ethers such as MTBE.

    摘要: Normal olefins such as n-butene can be converted to branched species by skeletal isomerization over catalysts containing solid acids prepared by sulfating catalyst precursors containing hydrous metal oxides--e.g., aluminas, silica-aluminas or clays treated with sulfuric acid, metal sulfates, sulfur trioxide or organic sulfates. The catalyst precursors are sulfated sufficiently to produce the desired skeletal isomerization without substantial cracking under suitable isomerization conditions.
