ABSTRACT:
A new catalyst for the selective conversion of isobutane to isobutylene. This catalyst also could be applied to the selective dehydrogenation of other light paraffins such as propane and n-butane. The catalyst is comprised of platinum, tin, and potassium supported on K--L-zeolite. This catalyst exhibits greater than 98% selectivity for conversion of isobutane to isobutylene at isobutane conversion levels greater than 50%. In addition, this catalyst exhibits excellent stability. The preferred catalyst would have an atomic ratio of Sn to Pt greater than 1.0 as well as an atomic ratio of K to Pt greater than 1.0.
