Abstract
An adsorptive catalyst for desulfurizing and denitrifying the fume generated by burning coal is composed of semi-coke from lignite, charrel coal, tar and Fe2(SO4)3. Its advantage is high mechanical strength.
Description
Technical field: the present invention relates to a kind of adsoption catalyst that is used to handle coal combustion generation waste gas, especially for the adsoption catalyst of coal-fired flue-gas dry desulfurization denitrogenation.
Background technology: China is coal big country, and coal is the most important energy of China.The atmosphere pollution of China is typical coal-smoke pollution, and seriously polluted, and its major pollutants are coal-fired sulfur dioxide and the nitrogen oxide that produces.Simultanously desulfurizing and denitrification is the inexorable trend of air contaminant treatment.At present, the development of desulfurization removing nitric adsoption catalyst simultaneously still belongs to the starting stage to the coal-fired flue-gas dry method, mainly is the charcoal absorption catalyst.Because the raw materials for production of active carbon are had relatively high expectations to process conditions, so the price of active carbon is expensive, and in addition, the active carbon mechanical strength is hanged down in regenerative process and easily pulverized, thereby has limited Application of Brand Active Carbon.
The object of the present invention is to provide the coal-fired flue gas desulfurization denitrogenation adsoption catalyst that a kind of price is low, mechanical strength is high.
Summary of the invention: component of the present invention and mass percent are: lignite semi-coke 55～60%, coking coal 20～25%, coal tar 10～15%, Fe
2(SO

36～10%.
At first lignite semi-coke is made in the brown coal destructive distillation, then lignite semi-coke, coking coal and coal tar are mixed according to the above ratio and extrusion modling, activate again and make activated carbon char, utilize catalyst Fe at last
2(SO

3Handle activated carbon char, obtain coal-fired flue gas desulfurization denitrogenation adsoption catalyst.
The coal-fired flue gas desulfurization denitrogenation adsoption catalyst of preparation is leans on shape, diameter 4～6mm, and high 8～12mm, desulfuration efficiency are between 92%～97%, and nitric efficiency is between 60%～80%.
With cheap brown coal is the coal-fired flue gas desulfurization denitrogenation adsoption catalyst that primary raw material is developed, and has reduced the adsoption catalyst cost.The adding coking coal has improved the mechanical strength of adsoption catalyst.
