The quenching process has the characteristics of complex pollutant composition, high purification difficulty, and serious environmental pollution. In order to meet national emission standards, coke tail gas containing SO2 must be treated. this paper, halloysite is selected as carrier, modified by low-temperature molten salt etching, manganese oxide supported hydrothermal method, formed chitosan gel microspheres, then treatment experiments are carried out. results show that: loaded reaction, its oxides mainly MnO 2, Mn2O3, MnO. When temperature 180 °C, metal loading ratio 5%, reaction 24 h, removal efficiency maintained at 79.47%, total desulfurization amount 73.22 mg. etching undergoes loading. Its 95.49%, 87.98
