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...

Catalyst supports based on ZnO–ZnAl2O4 nanocomposites with enhanced selectivity and coking resistance in isobutane dehydrogenation

“…2 d However, because of the high prices and low availability of platinum, and toxicity of Cr VI species, 4 development of alternative, low cost, and environmentally friendly catalysts is of great importance. In this respect, other catalysts based on gallia, 5 nickel, 6 cobalt, 7 zinc oxide, 8 etc . are currently being actively investigated for dehydrogenation of isobutane to isobutene.…”
