Cu基甲醇合成催化剂在两种模拟工业合成气中反应的结构变化及稳定性研究
Study on structure change and stability of Cu-based methanol synthesis catalysts in simulated reaction of two industrial syngas
摘要
Abstract
There are significant differences in the CO2 content of the synthesis gas obtained from different raw materials,but they can all be converted to methanol through the catalysis of traditional methanol catalysts.In order to study the effect of syngas with different CO2 content on the structure and performance stability of the catalysts,methanol synthesis was performed in an industrial-sized tubular jacketed reactor using simulated coal gasification and natural gas conversion syngas,and the changes of microparticles and catalyst performance stability of the original particle industrial catalysts before and after use were studied.The results show that the sizes of Cu and ZnO particles increase before and after the use of the five original industrial catalysts,and the sizes of Cu and ZnO particles increase faster under the conditions of synthetic gas produced by natural gas conversion.The overall performance of catalysts is limited,which is not conducive to maintaining the stability of catalyst performance.High CO2 content is more likely to destroy the stability of Cu+ and lead to the transformation of Zn species morphology.关键词
