Hydrogenation Study Of Benzene Over A Mo2c/Gamma-Al2o3 Catalyst By In Situ Ir Spectroscopy
Acta Physico-chimica Sinica（2014）
Abstract
Passivated, reduced passivated, and fresh Mo2C/y-Al2O3 catalysts were prepared by temperature-programmed reactions with a CH4/H-2 gas mixture. The results of in situ infrared (IR) analysis revealed that the fresh Mo2C/y-Al2O3 catalyst displayed the highest level of activity at room temperature, with cyclohexane being detected as the only product. The activity of molybdenum carbide in this reaction was comparable to that of the noble metals. The results from the in situ IR spectra for CO adsorbed onto the fresh Mo2C/y-Al2O3 catalyst before and after the hydrogenation of benzene showed that Mo2C was active for the hydrotreating processes and Mo delta+ (0More
