Effect of Lanthanide promoter on Methanol Synthesis Catalysts for Hydrogenation of CO and CO2 Mixtures

Abstract

Globally, research on reducing greenhouse gases such as CO2 is an important issue. Methanol is one of most traded chemicals in the world and is used for a variety of purposes such as raw material for chemical manufacturing or fuel for special vehicles. In this study, the methanol synthesis reaction using Cu-based catalyst was studied. The metal promoted Cu-based catalysts was prepared by the co-precipitation and the deposit precipitation methods. The prepared catalyst was characterized by N2 adsorption, H2-TPR, XRD, N2O adsorption technology. The effect of promotion is investigated on the performance of methanol synthesis catalysts. The methanol synthesis reaction was performed in a fixed bed reactor at low pressure conditions with different H2/CO/CO2 ratio in the feed mixtures.
