Cu/MgO催化剂CO加氢低温甲醇合成研究
LOW-TEMPERATURE METHANOL SYNTHESIS FROM CO HYDROGENATION OVER Cu/MgO CATALYST
摘要
Abstract
La and K promoted Cu/MgO catalysts were prepared by coprecipitation method. The catalytic performance of the catalysts on low-temperature methanol synthesis from CO2 -containing syngas was investigated. The catalysts were characterized by means of XRD and TPD measurements. The results indicated that La2O3 addition improved Cu dispersion, which enhanced the low temperature CO and CO2 adsorption ability and promoted the conversion of CO2. With the further addition of K2O, the improved surface basicity caused an increase in CO and CO2 high temperature adsorption. The simultaneous conversion of CO and CO2 was achieved, and the activities of the catalyst and methanol yields were enhanced, while the selectivity of ethyl formate was increased. The catalyst with Cu/K molar ratio of 10 :1 showed high activity and stability, and the total carbon conversion of 29. 7% was obtained with high methanol yield.关键词
