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

Addition of Pt and K to Ga 2 O 3 /Al 2 O 3 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 CrO x and Pt-Sn, the catalyst performance of the supported Ga-...

Summary:Addition of Pt and K to Ga 2 O 3 /Al 2 O 3 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 CrO x and Pt-Sn, the catalyst performance of the supported Ga-Pt-K catalyst only marginally changed after 3 hours of dehydrogenation. Gallia/alumina promoted with tiny amounts of Pt and K exhibits superior stability in butane dehydrogenation compared to commercial catalysts.
