Title: Isomerization of n-butane on Pt/SO{sup 2{minus}}{sub 4} - ZrO{sub 2} and mechanical mixtures of Pt/Al{sub 2}O{sub 3} + SO {sup 2{minus}}{sub 4} -ZrO{sub 2}

Abstract

The effect of the incorporation of a metallic phase (Pt) into a superacid catalyst (SO {sup 2{minus}}{sub 4} - ZrO{sub 2}) for n-butane isomerization was studies. The convenience of supporting Pt directly on the super-acid or on alumina and of using the physical mixture as a catalyst was also analyzed. Pt supported on SO {sup 2{minus}}{sub 4} -ZrO{sub 2} has the same activity as So{sup 2{minus}}{sub 4} -ZrO{sub 2}, but the stability is increased. The bifunctional reaction mechanism is not operating because Pt does not have the metallic properties due to a strong interaction with the support under the experimental conditions of reduction (573 K). When Pt is supported on Al{sub 2}O{sub 3} and mixed mechanically with SO{sup 2{minus}}{sub 4} -ZrO{sub 2}, the activity and stability are increased due to the operation of the bifunctional mechanism. 14 refs., 5 figs., 3 tabs.
