Description

1. Technical field

[0001] The invention relates to a method for desulfurizing waste gas, in particular to a method for desulfurizing waste gas containing hydrogen sulfide and organic sulfur. The invention also relates to a special desulfurizing agent for desulfurizing waste gas containing oxygen and a preparation method thereof. The invention belongs to the technical field of exhaust gas purification and treatment. 2. Background technology

[0002] Generally speaking, there are two types of gas desulfurization, one is the removal of sulfur oxides, and the other is the removal of hydrogen sulfide and organic sulfides. Usually, sulfur oxides exist in oxidizing atmospheres, such as flue gas, etc., hydrogen sulfide and organic sulfides usually exist in reducing atmospheres, such as natural gas, synthetic ammonia raw material gas, etc. The use of solid desulfurizers is a common way of gas desulfurization, and the desulfurizers required for different exhau...
