A new low-temperature methanol synthesis process from low-grade syngas

摘要

The low-temperature methanol synthesis from syngas containing CO_2 with Cu/ZnO catalysts was carried out under 443 K and 50 bar in a semi-batch flow-type reactor with the aid of alcohol. The high one-pass total carbon conversion (61%) and methanol selectivity (>98%) were achieved without the deactivation of catalyst. The low-temperature methanol synthesis is feasibly promising for various kinds of syngas, therefore, it is facilely applied to an industrial process.
