Abstract

Abstract: The effect of quantity, composition, and different impregnation sequences on the catalytic properties of Cu‐Zn‐Al/SiO2 ‐TiO2 in the CO2 hydrogenation for methanol production was investigated. The Cu‐Zn‐Al catalysts supported on SiO2 and TiO2 were prepared by incipient wetness impregnation. Then, their performances in CO2 hydrogenation were tested under defined conditions. The composition variation of Cu and Zn catalysts resulted in a high methanol production for Cu catalysts with a higher content of Cu, which was the active site for CO2 activation. Regarding the metal quantity of catalysts, a relatively low loading of co‐metal (Cu‐Zn‐Al) led to the maximum methanol yield when compared with higher loadings as a result of the largest surface area. Abstract : CO2 can be used as a low‐cost carbon source for hydrogenation reactions that is converted to alcohols, hydrocarbons etc. The influence of quantity, composition, and different impregnation sequences on the catalytic properties of Cu‐Zn‐Al catalysts on a SiO2 ‐TiO2 support was evaluated for CO2 hydrogenation to methanol. Cu plays a major role in this process.
