Studies of methanol conversion over HZSM-5 using /sup 13/C-labeled methanol in the presence of various olefins and aromatics revealed the importance of desorption limitation of reaction intermediates, as evidenced by extensive multiple labeling of polymethylbenzenes produced from unlabeled toluene. These studies also indicated that most of the ethylene produced from methanol is not a primary C/sub 1/ coupling product, but rather a secondary product derived from methyl attack on C/sub 3//sup +/ olefins, as evidenced by the predominant formation of singly labeled ethylene. A classical carbenium ion mechanism incorporating these findings is presented for the conversion of methanol to hydrocarbons over HZSM-5.
