Pt-and K-promoted supported gallia as a highly stable alternative catalyst for isobutane dehydrogenation

Abstract

Addition of Pt and K to Ga2O3/Al2O3 was shown to be beneficial for isobutane dehydrogenation. This catalytic system can be successfully realized in both fluidized and fixed-bed reactors. In contrast to supported catalysts based on CrOx and Pt-Sn, the catalyst performance of the supported Ga-Pt-K catalyst only marginally changed after 3 hours of dehydrogenation.
