Olefin isomerization using a cobalt-sulfur catalyst

摘要

Double bond isomerization of olefins utilizing a catalyst comprising cobalt and sulfur on a porous carrier; the catalyst being prepared by forming an initial composite of the cobalt with the carrier material, sulfiding the initial composite to provide a sulfur/cobalt atomic ratio of at least about 1 in the sulfided composite, and then stripping sufficient sulfur from the sulfided composite with hydrogen to provide a final isomerization catalyst composition having a sulfur/cobalt atomic ratio of less than about 1 and more than about 0.55.
