STUDY OF Cu Mu CATALYST FOR THE SYNTHESIS OF METHYL FORMATE AND METHANOL FROM SYNTHESIS GAS

A new Cu Mn catalyst has been developed for the synthesis of methyl formate and methanol from synthesis gas. The catalyst exhibited a fascinating reaction activity and methyl formate selectivity. Over the catalyst, it was observed that methyl formate selectivity decreased apparently with the increase of reaction temperature and pressure. Furthermore, the reaction activity increased at first, then decreased with the increase of reaction temperature, while increased when the reaction pressure was up. The experimental results suggest that the direct synthesis of methyl formate from synthesis gas is possible. Moreover, the methyl formate selectivity was fairly high. Also, the influence of catalyst preparation method and deactivation reason of Cu Mn catalysts were investigated by using XRD patterns and XPS Auger technique.
