Advance in ethanol synthesis from syngas via carbonylation of dimethyl ether and hydrogenation of methyl acetate

doi:10.11949/0438-1157.20210079

Abstract

Abstract:

As a new method for ethanol synthesis from coal, dimethyl ether carbonylation with CO to methyl acetate and its further hydrogenation to ethanol has attracted much industrial attention. This route requires mild reaction condition and the catalysts can be easily prepared. In this work, we reviewed the advancement of the catalyst in the field of dimethyl ether carbonylation and methyl acetate hydrogenation. In addition, we summarized the effect of proximity of zeolite and Cu-based catalyst for ethanol synthesis. We especially focused on the development of dimethyl ether carbonylation and deactivation mechanism over zeolite as well as the modification methods of zeolite. The new coal-to-ethanol technology provides an important way for the clean and high-value-added utilization of coal resources in China.

Key words: ethanol, dimethyl ether, carbonylation, methyl acetate, zeolite, Cu-based catalyst
