ABSTRACT:
The selective conversion by skeletal isomerization over steam pretreated ferrierite zeolite-based catalysts having pore sizes of at least about 4.2 Angstroms and a pore structure characterized by intersecting 10-MR and 8-MR channels. The steam pretreated ferrierite zeolite-based catalysts have sufficient acidity to catalyze the skeletal isomerization of normal olefins. The catalysts can be used to produce isoolefins for reaction with alcohols in integrated processes to produce tertiary amyl methyl ethers such as TAME.
