Compared to Pd/SiO2, Mo2C showed similar hydrogenation rate for 1,3-butadiene and 1,3-CHD and even higher rate for 1,4-CHD, but with significant deactivation rate for 1,3-CHD hydrogenation. However, the hydrogenation activity of Mo2C could be completely regenerated by H2 treatment at 723K for the three molecules. The Ni modified Mo2C catalysts retained similar activity for 1,3-butadiene hydrogenation with significantly enhanced selectivity for 1-butene production. The 1-butene selectivity increased with increasing Ni loading below 15%. Among the Ni modified Mo2C catalysts, 8.6% Ni/Mo2C showed the highest selectivity to 1-butene, which was even higher selectivity than that over Pd/SiO2. Compared to Pd/SiO2, both Mo2C and Ni/Mo2C showed combined advantages in hydrogenation activity and catalyst cost reduction, demonstrating the potential to use less expensive carbide catalysts to replace precious metals for hydrogenation reactions.
