모사 합성가스를 이용한 메탄올 합성 연구

Abstract

The effects of catalyst content, reaction temperature, gas composition, and pressure on the activity and selectivity of Cu/ZnO/Al2O3 catalyst for the methanol synthesis have been investigated in a high pressure fixed bed reactor. Methanol yield shows a maximum value at around 250oC and increases with increasing reaction pressure. Among the catalysts used, Cu/ZnO/Al2O3(49:16:15) showed the highest catalyic activity. The methanol yield increases with increasing CO2 concentration up to 10% and then decreases with the increase of CO2 concentration due to the strong adsorption of H2O and CO2 on the active site of catalyst.
