Molybdenum carbide exhibits some properties similar to those of noble metals, and study of it in the field of catalysis has attracted more attention due to its recent development. Molybdenum carbides have been reported to be active for synthesis of light hydrocarbons in the liquefied petroleum gas rang from carbon monoxide and hydrogen at atmospheric pressure.Promotion of molybdenum carbide with K2CO3 has been found to greatly enhance the selectivity to alcohols composed of linear C1-C7. It thus appears that molybdenum carbide could be a potential catalyst for alcohol synthesis.In particular, the beneficial effect of Co has not been fully explored. Thus, in the present paper, K/beta-Mo2C catalysts modified by Co were prepared and tested for HAS from CO hydrogenation. It showed a high performance for HAS, and the characteristics of K/Co/beta-Mo2C for mixed alcohols synthesis from syngas are also investigated.
