摘要：

Reaction residue retained by H-ZSM5 from treatment with benzene and toluene in the presence of oxygen (O2/N2 = 1/99-20/80) at 573-773 K has been studied. Retained product contained both oxygenates and hydrocarbons, the latter being similar to those obtained in the presence of oxygen, although oxygen caused some increase in anthracenes/phenanthrenes. Probable pathways for the formation of the main classes of oxygenates are discussed. The acidity of the H-ZSM5 is essential in that very little reaction occurred with silicalite.
