摘要： Double bond isomerization of olefins utilizing a catalyst comprising nickel and sulfur on a porous carrier; the catalyst being prepared by forming an initial composite of the nickel with the carrier material, sulfiding the initial composite to provide a sulfur/nickel atomic ratio of at least about 0.9 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/nickel atomic ratio of less than about 0.9 and more than about 0.55.
