Abstract
An improved process is disclosed for the isomerization of butenes and/or pentenes using a catalyst comprising a silicoaluminophosphate molecular sieve containing noncondensed silica. It is of particular interest to increase the proportion of olefins containing tertiary carbons in the product with low formation of undesirable by-products. Product olefins may be further processed to obtain ethers, which enjoy high current interest as components for reformulated gasoline.
