Removal of toluene from industrial gas over 13X zeolite supported catalysts by adsorption-plasma catalytic process

摘要: BACKGROUND To find an appropriate catalyst in the adsorption plasma catalytic process, degradation of toluene over 13X zeolite supported catalysts were studied. RESULTS 13X exhibited excellent capacity but weak ability. After loading Cu, Co, Ce and Mg active compounds by impregnation method, was reduced performance significantly improved. Co/13X good performance, which carbon balance 81.6% with 74.4% COx for 0.51 mmol. Effect cobalt value calcination temperature studied, found that 5% 500 °C more optimal temperature. The characterization results BET, FTIR, XRD, XPS SEM correlated performance. CONCLUSIONS The block pores reduce specific surface area zeolite, sites can decompose ozone to produce atomic oxygen species. Co3+ could form π-complexation bonding Co3O4 is P-type semiconductor, has large converts into O− O2− easily. presented point catalytic.
