Abstract

The embodiment of the invention provides a supported desulfurization catalyst and a preparation method of the supported desulfurization catalyst. The supported desulfurization catalyst comprises, for example, a porous alumina carrier and aminocarboxylic acid complex iron ions supported on the surface of the porous alumina carrier. The specific surface area of the porous alumina carrier is 50-500 square meters per gram, the average pore volume of the porous alumina carrier is 0.05-0.8 cubic centimeters per gram, and the average pore size of the porous alumina carrier is 0.5-50 nanometers. The supported desulfurization catalyst provided by the embodiment of the invention is suitable for desulfurization of to-be-desulfurized gas containing hydrogen sulfide and oxygen, can oxidize hydrogen sulfide into elemental sulfur, has higher desulfurization performance, and is suitable for a desulfurization environment with higher reaction temperature and higher oxygen concentration.

Description

technical field

[0001] The invention relates to the technical field of gas purification and environmental protection, in particular to a loaded desulfurization catalyst and a preparation method of the loaded desulfurization catalyst. Background technique

[0002] Raw material gases such as blast furnace gas (also known as blast furnace gas) or coke oven gas (also known as coke oven gas) are produced in iron and steel smelting, coal chemical industry and other production processes, which contain hydrogen sulfide (H 2 S) gases, even organic sulfides (such as carbonyl sulfide, which produce H after hydrolysis 2 S), high concentration of H 2 The existence of S not only pollutes the environment, corrodes pipeline equipment, and affects product quality, but also causes catalyst poisoning and deactivation in subsequent process production, so H in the gas phase is removed 2 S is a very important process. At present, the existing desulfurization catalysts have low desulfurization ...
