Abstract：A series of V2O5/ACH catalysts were prepared by supporting V2O5 on activated carbon honeycomb (ACH). Silicate and phenolic resin were used as binders, respectively. Two types of V2O5/ACH catalyst were studied for simultaneous SO2 removal and NO conversion. The results indicate that the silicate binder affects the amounts of carbon and alkali metal oxides in the catalyst and subsequent SO2 removal and NO conversion rates, therefore, the ACH with higher carbon and lower alkali metal oxide contents is preferred. The catalyst with phenolic resin has high carbon amount and micropore volume, and hence higher SO2 removal rate, but lower NO conversion rate. The high proportion of oxygen and carbon in the ACH with the silicate results in improvement of NO conversion. However, the silicate decreases SO2 removal rate by reducing the micropore quantity of ACH and decreasing the specific surface area and micropore volume of the catalyst. Under the optimal conditions of ACH with 30% silicate or with phenolic resin carbonized at 900℃, over 90% NO conversion rate for the catalyst with the silicate can be reached, and SO2 capacity for the catalyst with phenolic resin is 7.3%(w).
