Iron compound catalyst for inhibiting generation of dioxin and incineration process of municipal solid waste using the same

摘要

A catalyst for inhibiting the generation of dioxin, which catalyst comprises iron oxide and/or iron oxide hydroxide particles having: an average particle size of 0.01 to 2.0 mu m, a BET specific surface area of 0.2 to 200 m<2>/g, a phosphorus content of not more than 0.02 % by weight, a sulfur content of not more than 0.6 % by weight and a sodium content of not more than 0.5 % by weight; and the catalyst being capable of converting not less than 15% of carbon monoxide into carbon dioxide when 2.8 x 10<-4> mol of iron oxide particles obtained by heat-treating the catalyst in air at a temperature of 800 DEG C for 15 minutes are instantaneously contacted with 6.1 x 10<-7> mol of carbon monoxide at 250 DEG C and a space velocity (SV) of 42,400 h<-1> in an inert gas atmosphere using a pulse catalytic reactor.
