摘要：

Natural gas is a green and efficient energy source, which has taken an increasing part of energy structure in China. Since natural gas contains a certain amount of toxic and harmful gas, hydrogen sulfide, it needs to be desulfurized before its utilization. Biological desulfurization is a process in which sulfur compounds are removed from gas and wastewater using microorganisms. Biodesulfurization is a simple process that has mild operating conditions, low energy consumption, less environmental pollution, high desulfurization efficiency and sulfur by-products. Therefore, the biological desulfurization technology has been one of research spots in the natural gas sweetening process. The review briefly summarizes the main sources of hydrogen sulfide in natural gas and natural gas desulfurization technologies used widely in industry, and then mentions the main bacterial strains used for biological desulfurization and their desulfurization metabolic pathways. Herein, the typical process and new process of natural gas biological desulfurization technology are described emphatically. Finally the developing trends of natural gas biological desulfurization technology are pointed out. © 2021, Chemical Industry Press Co., Ltd. All right reserved.
