Description

technical field [0001] The invention belongs to the field of activity evaluation of desulfurization catalysts, and in particular relates to an activity evaluation device and method of desulfurization catalysts. Background technique [0002] Blast furnace gas contains flammable gases such as carbon monoxide, hydrogen, methane, etc., which contains about 23-30% carbon monoxide, 12-16% carbon dioxide, 0.8-1.9% hydrogen, 0.6-1.8% oxygen, 0.4- About 0.8% methane, 200mg / Nm 3 About COS, 50mg / Nm 3 left and right H 2 S and about 50% nitrogen. Blast furnace gas without desulfurization treatment will emit more than 200mg / Nm after combustion 3 SO 2 , directly discharged into the atmosphere, will cause the formation of acid rain and seriously pollute the environment. With the increase of people's awareness of environmental protection, the emission limit of sulfur has become increasingly strict, and each terminal using blast furnace gas has established a huge flue gas desulfurizatio...
