STUDY OF A NEW LOW-TEMPERATURE METHANOL SYNTHESIS ON Cu/ZnO/Al_2O_3 CATALYSTS FROM CO/CO_2/H_2 USING 2-BUTANOL PROMOTER

摘要

Methanol, which is a fundamental chemical and fuel for fuel cell or vehicle, is being produced by 30 million ton per year around the world from CO/CO_2/H_2. Methanol is industrially produced under high temperature and high pressure, using a copper-zinc-based oxide catalyst. However, the efficiency of methanol synthesis is severely limited by thermodynamics because methanol synthesis is an extremely exothermic reaction [1,2]. Therefore, developing a low-temperature process for methanol synthesis will greatly reduce the production cost and high CO conversion becomes available at low temperature.
