Through the use of /sup 14/C-labeled tracer compounds, some important secondary reactions have been identified in the overall conversion of methanol to hydrocarbons over a Ni-ZSM-5 catalyst. The major findings are: the alkylation of light olefins with methanol or dimethyl ether is a major pathway for the formation of larger olefins with one more carbon atom; paraffins are mainly produced by hydrogen transfer reactions to their corresponding olefins, i.e., ones having the same carbon skeleton; except for minor cracking reactions, paraffins with up to at least 7 C atoms are final stable products; isomerization among paraffin isomers does not take place at 368/sup 0/C; light olefins, e.g., ethylene, propylene, and butenes, are reactive intermediates for aromatics formation; and aromatic compounds can also be produced by methanol- or di-methyl ether-alkylation of benzene and subsequent alkylated benzenes.
