Abstract

Mo2C prepared by the carburization of MoO3 with a C2H6/H2 mixture is an effective catalyst for the decomposition of both ethanol and methanol. The total decomposition of both compounds was attained at 573-623 K. The selectivity of H2 production in the decomposition of ethanol was 40-45% even at 723 K. With regard to die formation of H2, more attractive results were obtained in die case of methanol decomposition when H2, with a selectivity of 60%, was the major product. An important feature of this catalyst is the high thermal stability at 573-723 K. Adding water to methanol somewhat decreased the content of CO and increased that of H2 in the products. The highest yield of H2 production, ∼75%, was reached at 723 K.
