ABSTRACT:
A process for the isomerization of butenes in a mixed hydrocarbon stream containing butene-1, butene-2 and small amounts of butadiene in which the mixed hydrocarbon stream is fed to distillation column reactor containing an alumina supported palladium oxide catalyst as a distillation structure. As butene-1 is produced it is distilled off upsetting the equilibrium and allowing for a greater than equilibrium amount of butene-1 to be produced. Additionally, any butadiene in the feed is hydrogenated to butenes. The bottoms, which is rich in butene-2 may be recycled to the reactor column for more complete conversion of butene-2 to butene-1. Alternatively, a portion or essentially all of the bottoms, substantially free of butadiene, may be used for feed to an HF alkylation unit.
