ABSTRACT:
An improved process is disclosed for the isomerization of pentenes in the absence of hydrogen using a catalyst comprising a non-zeolitic molecular sieve. 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 methyl t-amyl ether, which enjoy high current interest as components for reformulated gasoline. Pentenes in raffinate from etherification may be returned to the isomerization process.
