Hydrogenation of CO_2 over Cu-based catalysts Promoted by additive of co in the feed

摘要

Methanol synthesis from CO_2 hydrogenation over Cu-Zn-al catalysts was studied. The addition of a small amount of CO in the feed resulted in the increase of methanol selectivity and yield. The results of TPD and TPSR indicated that CO occupied the active sites, thus suppressed the reverse water-gas reaction of CO_2 and enhanced the formation of methanol.
