Abstract

The invention belongs to the field of the utilization of blast furnace slag, and particularly relates to a preparation method of a novel SCR smoke denitrification catalyst adopting titanium-containing blast furnace slag as a carrier. The preparation method comprises the following steps: a, pretreating the titanium-containing blast furnace slag; and b, preparing the catalyst. The preparation method of the catalyst is simple and easy in operation, high in blast furnace slag utilization rate, capable of effectively solving the resource waste and environmental pollution problem caused by the extensive application of the titanium-containing blast furnace slag and capable of enlarging the application field of the blast furnace slag; the catalyst prepared in the method is high in activity, wide in active temperature window and capable of maintaining relatively high denitrification activity at the temperature of 160 to 260 DEG C.

Description

technical field

[0001] The invention belongs to the utilization field of blast furnace slag, and in particular relates to a preparation method of a novel SCR flue gas denitrification catalyst using titanium-containing blast furnace slag as a carrier. Background technique

[0002] Nitrogen oxides (NO x ) is one of the main pollutants in the atmosphere, which will cause many harmful social and environmental problems such as acid rain and photochemical smog. The main source of nitrogen oxides is the combustion of fossil fuels, and nearly 90% of my country's current energy structure is fossil energy. Therefore, the reduction and control of nitrogen oxides is the main and urgent task of my country's air pollution prevention and control. Since 2000, my country's coal-fired power plants have developed rapidly, and the emissions of nitrogen oxides have also increased significantly. The annual emissions of nitrogen oxides in the power industry account for about 70% of the total emis...
