ABSTRACT
Sulphur dioxide is one of the main pollutants in the atmosphere, toxic and pungent, mainly from the burning of coal and oil. Sulfur dioxide emissions from power plants are high, and the current method of wet desulphurization has its drawbacks. By contrast, direct catalytic reduction has great advantages, which can reduce the pollution problem and solve the shortage of sulfur in our country.
This article USES the bottled sulfur dioxide, carbon monoxide and nitrogen gas as the main raw materials, distribution, use of catalyst to improve the reaction rate, three kinds of gas mixture was used to simulate the plant actual situation, get the yield of elemental sulfur, and analyze the product composition. Carbon monoxide as the reducing agent of desulfurization slow progress of industrialization, mainly concentrated in the laboratory of continuous exploration stage, this experiment aims to get through the process of continuous intake, do matting for engineering to promote. For the yield of elemental sulfur detection before and after the reaction of SO2 concentration, the concentration of sulfur dioxide flue gas analyzer can be used for testing, due to the high concentration of sulfur dioxide in the simulating test, can use nitrogen to dilute, let SO2 concentration in flue gas analyzer to measure the concentration range.
Key words： Sulfur dioxide; Carbon monoxide; Nitrogen; Catalytic reduction; sulfur
