Replacing Platinum with Tungsten Carbide for Decalin Dehydrogenation

Abstract

Pt was replaced with tungsten carbide (WC) in the Ni–Pt structure for decalin dehydrogenation on base of their similar properties. The catalytic performance of Ni–WC catalyst was predicted by density functional theory (DFT) calculations and further confirmed by dehydrogenation reaction. Replacing Pt with WC significantly reduces the side reactions such as ring-opening and coking. The highest conversion of decalin is about 93 % and the selectivity to naphthalene is nearly 100 % over Ni–WC/AC catalyst. The improved catalytic activity of Ni–WC/AC demonstrates the feasibility to replace Pt with WC as an active and less expensive dehydrogenation catalyst.
