Continuous synthesis process of methanol at low temperature from syngas using alcohol promoters
摘要
A continuous process for low-temperature methanol synthesis from CO/CO2/H2 based on the promoting effect of alcohol solvent has been developed. 2-butanol, acting as a promoter, with the aid of Cu/ZnO solid catalyst, realized the high efficient synthesis of methanol with one-pass methanol yield of 47.0%and methanol selectivity of 98.9%at temperature as low as 443 K and 50 bar, which can be a very promising method for methanol production at low temperature.
