英文摘要 | the coupled reaction of n-hexane and methanol was studied and compared with the reactions of individual reactants over hzsm-5 zeolite catalyst. the catalytic reaction test results and the temperature-programmed surface reaction (tpsr) results showed an improvement of the initial n-hexane activity when methanol was used as co-reactant. the ft-ir analysis indicated that methanol was adsorbed on acid sites prior to n-hexane and immediately transformed into surface methoxy groups. these species acted as the active sites for the conversion of n-hexane and improved the initial activity of n-hexane by bimolecular hydride transfer. the catalytic test also suggested that alkenes resulting from the transformation of methanol further enhance the conversion of n-hexane, in addition to the improvement by metboxy groups. a faster conversion of methanol was also observed in the coupled system, which highlights a bidirectional promotion effect of the coupled reaction. a reaction mechanism is proposed to explain all observations.
