IRON COMPOUND CATALYST FOR INHIBITING GENERATION OF DIOXIN AND INCINERATION PROCESS OF MUNICIPAL SOLID WASTE USING THE SAME

摘要

The invention of the 2.8 × 10 ^-4 mol of iron oxide particles obtained by heat-treating the iron compound catalyst for 15 minutes in a 800 ℃ air in an inert gas atmosphere at 250 ℃ and space velocity (SV) of 42,400h ^-1 pulse catalytic reactor using a 6.1 × 10 ^-7 mol of carbon monoxide and the moment when the contact, for 15% or more of carbon monoxide to iron oxide that has a catalytic activity that can be converted to carbon dioxide particles, iron oxide hydroxide particles or inhibiting generation of dioxin, which comprises a mixture of these particles It relates to an iron compound catalyst provided for;; In the iron oxide particles or iron oxide hydroxide particles having an average particle diameter of 0.01 to 2.0㎛, BET specific surface area of ​​0.2 to 200㎡ / g, the amount is 0.02 weight% or lower, a sulfur content less than 0.6% by weight phosphorus and less than the sodium content of 0.5% by weight to be. The iron compound catalyst is mechanical batch incinerators or semi-continuous, and can be completely burning municipal solid waste during the intermittent low temperature combustion in the municipal solid waste incinerator, which operates as in the incinerator and decomposition dioxin precursors, the large-scale incinerator renovation or plant and equipment when low temperature combustion at the start-stop operation of the incinerator or without investment can prevent the generation of dioxin due to the memory effect.
