摘要: 采用动态原位红外测试技术和TPD、TPSR方法,系统地研究了合成甲醇有关物种H_2、CO、CO_2和CH_3OH在铜基催化剂上的吸附与反应特性,判识了反应过程中在催化剂活性表面上的吸附态中间物的类型。在实验信息的基础上,提出了在催化剂活性表面上可能的基元过程序列结构。

Abstract: The adsorbability and reaction features of related reactants, such as CO, CO2, CH3OH and H2, were investigated by using the in - situ FTIR analysis technique and TPD, TPSR methods. Based of the analysis of experimental information involved in methanol synthesis, an elementary step sequence for methanol synthesis over a commercial copper - based catalyst, MK - 101, was proposed, which was the basis of developing a dynamic kinetic model by using transient response technique.
