Description

Technical field [0001] The present invention relates to the field of blast furnace gas desulfurization techniques, and more particularly to a blast furnace gas organic sulfur conversion device, a blast furnace gas organic sulfur conversion method and an organic sulfur conversion catalyst regeneration method. Background technique [0002] In the prior art, the blast furnace gas is generally delivered to the power plant boiler, the refining plant hot air furnace, steel mills, etc., which are used as fuel, and the production is large and widely used. At present, the blast furnace gas is not directly used as a fuel use of other devices in the plant, which can cause SO in flue gas emissions of each device. 2 The content exceeds the national ultra-net emission requirements, and the environmental protection pressure of each steel plant is huge. [0003] Since sulfur in blast furnace gas is mainly organic sulfur, hydrogen sulfide only occupies less, h 2 S can be removed by alkaline washi...
