DME synthesis from biomass-derived syngas in a slurry-bed reactor
摘要
Abstract
Dimethyl ether (DME) synthesis from biomass-derived syngas in a slurry-bed reactor was investigated over a hybrid catalyst composed of methanol synthesis catalyst and molecular sieve. The results showed that the catalyst containing SAPO-11 exhibits higher DME selectivity and catalytic stability, which is closely related to the weak acidity of SAPO-11 in the hybrid catalysts. 40% CO conversion and 95% DME selectivity in organic products could be kept during 35 h stability test over the hybrid catalyst when the weight ratio of methanol synthesis catalyst to SAPO-11 was 3.关键词
