Impregnation method was established

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)

  1. 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

  2. Nano(M)-ZSM-5

  3. Nano(M)-ZSM-5

  4. (SnO)4-Al2O3 -HT

  5. (SnO)4-Al2O3 -HT

  6. SnO-(Al2O3)2 -MO

  7. SnO-(Al2O3)2 -MO

  8. SnO-(Al2O3)2 -MO

  9. SnO-(Al2O3)2/nano(M)-ZSM-5

  10. Nano-ZSM-5 MO(SnAl4)-Nano-ZSM-5 Nano(p)-ZSM-5

  11. Nano-ZSM-5 MO(SnAl4)-Nano-ZSM-5 SnO-(Al2O3)2(BB)/Nano(M)-ZSM-5

  12. Future works • Synthesize Sn-ZSM-5 crystal (impurity level of SnO) • Loading SnO only on ZSM-5 • Loading SnO-Al2O3 at pH 7.0 with higher T & longer aging time Used SnO-(Al2O3)2/nano(M)-ZSM-5

  13. Used SnO-(Al2O3)2/nano(M)-ZSM-5

  14. Used SnO-(Al2O3)2/nano(M)-ZSM-5
