Abstract: With the proposed goal of "carbon peak" and "carbon neutrality", the Chinese government has increasingly strict requirements for the waste gas treatment of sulfur-containing industries. As a clean and low-carbon fossil energy, natural gas is an important part of the construction of China's new energy system. H₂S, a colorless highly toxic gas, widely exists in natural gas, which will have great damage to the health of equipment and mining personnel during its mining process, so the removal of H₂S in natural gas is very important. The research progress of H₂S removal technology from natural gas is reviewed, the technical characteristics of the method are summarized, and the new desulfurization technology is prospected, which can provide ideas for the development of desulfurization technology.

Key words: natural gas, hydrogen sulfide, wet method, dry method, new desulfurization technology
