摘　　要：概括了甲醇转化反应机理实验和理论研究方法,介绍了甲醇脱水预平衡阶段的主要机理模型和实验理论依据,重点综述了C-C键形成过程中涉及到的直接机理和"烃池"机理的实验与理论研究进展和存在的问题,探讨了分子筛孔道结构对"烃池"物种结构和反应历程的影响。This review introduces the recent progresses made in the study of direct reaction and hydrocarbon- pool mechanisms for the C-C bond formation in the conversion of methanol over acid molecular sieves. It also involves in the main theoretical and experimental methods. The dehydration mechanism of methanol and the problems of direct reaction and hydrocarbon-pool mechanisms are also analysed. In addition, the effect of molecular sieve pore structures on the hydrocarbon-pool species and their reaction mechanism was evaluated.
