Presentation transcript:

Impregnation method was established Thin layer of metal oxides can be formed on ZSM-5 surface by incipient impregnation method No other structure observed from the metal oxide coated ZSM-5 (SEM, XRD) Catalytic activity was not sufficient (except SnO-Al2O3) - catalytic activity reason (Calc. Temp, metals) - low reaction temperature reason Search better metal oxides for the reaction CeO2, NiO, VO, CaO, etc
