The dehydrogenation of bicyclohexyl as a liquid organic hydrogen carrier on supported Pt/Sibunit catalysts based on the neutral and partially oxidized supports at a temperature of 320 °C and a space velocity of up to 1.5 h−1 was studied. The oxidized Sibunit is a more effective support for Pt catalyst in terms of TOF, conversion and selectivity than the neutral carrier. The 3 wt% Pt catalyst shows a higher conversion and selectivity to biphenyl than the 0.5 wt% Pt catalyst on both carriers, but TOF of 0.5 wt% Pt catalyst reaches 238 and 182 mol(H2)/(gPt * min) for 4 h of the reaction on oxidized Sibunit and neutral Sibunit, respectively. The TOF are 47 and 42 mol(H2)/(gPt * min) for the corresponding catalysts with a 3 wt% Pt loading.
