The reaction of ethanol was investigated on Mo2C, Mo2C/SiO2 and Mo2C/ZSM-5 catalysts at temperature ranging 573-973 K under atmospheric pressure. Mo2C and Mo2C/SiO2 catalyzed only the decomposition of ethanol to H-2, ethylene, acetaldehyde and different hydrocarbons. The main reaction pathway on pure ZSM-5 is the dehydration reaction yielding ethylene, small amounts of hydrocarbons and aromatics. Deposition of Mo2C on zeolite greatly enhanced the yield of benzene and toluene by catalyzing the aromatization of ethylene formed in dehydration process of ethanol.
