Secondary reactions have been identified in the overall conversion of methanol to hydrocarbons over a Ni-ZSM-5 catalyst. The major conclusions are: (1) The alkylation of light olefins with methanol or methyl ether is one pathway for the formation of larger olefins with one more carbon atom. (2) Paraffins are produced primarily by hydrogen transfer to the corresponding olefin. (3) Except for minor cracking reactions, paraffins with no more than 7 carbon atoms, are final stable products; isomerization among paraffin isomers does not take place at 368/sup 0/C. (4) Light olefins, e.g. ethylene, propylene, and butenes, are reactive intermediates for aromatics formation. (5) Aromatic compounds may also be produced by methanol- methyl ether-alkylation of benzene and subsequent alkylated benezenes. 2 figures, 3 tables.
