Butane Dehydrogenation Catalyst

HTPB-DH butane dehydrogenation catalyst is a newly developed high efficient catalyst used for isobutane dehydrogenation to produce isobutene. The isobutane conversion and isobutene selectivity can reach a high index in moderate conditions. The main physical and chemical properties and the performance of reaction are shown in the table 1 and table 2.
