Abstract:
Conversion of CH4, C2H6, C3H8, benzene and their binary mixtures over H-NaZSM-5 catalyst in the presence of N2O was studied. It was found that under experimental conditions methane alkylates benzene to give toluene and xylenes. Acidity of the catalyst had no effect on the reactivity of active oxygen formed from N2O towards methane and benzene, but affected their secondary transformation. Acidic samples favored the reaction of aromatic ring methylation with methane whereas deep oxidation of CH4 prevailed on NaHZSM-5. Based on the relative reactivities and C-13 label distribution in the products of (CH4)-C-13+C6H6+N2O feed conversion, the scheme of hydrocarbon transformation was proposed.
