- 中文摘要: The reaction mechanism of methanol conversion to hydrocarbons on HZSM-5 zeolite was studied. From the selectivity plots of products in an integral fixed-bed flow reactor, paraffins were classified as primary and secondary stable products, light olefins as primary unstable products, aromatics as primary and secondary unstable or stable products. The results of the /sup 14/C-labelled methanol reaction indicated that the C/sub 1/-C/sub 5/ surface intermediates generated by dimethyl ether/ methanol equilibrium gave paraffins and olefins at 300.degree.C. The concentration of intermediates and adsorbed methanol on ZSM-5 decreased with increasing temperature. The distribution of radioactivity showed that propylene played an important role in the autocatalysis of the reaction.
