摘要：The removal of hydrogen sulphide by using the method of dry desulphurization in a normal temperature ironoxide is introduced in this paper. The experiment has been conducted by using the ferric oxide as thedesulphurizer in the waste red mud and added wood chips and calcium oxide for the removal of hydrogensulphide. Also, the desulphurization efficiency of desulphurizer is researched in different drying temperaturesand different ratio conditions, and the best condition of removing hydrogen sulphide is studied. The resultsof the studies show that the best conditions of removing hydrogen sulphide are 80% of red mud, 5% of woodchips and 15% of calcium oxide at 110°C drying temperature; 85% of red mud, 5% of wood chips and 10%of calcium oxide at 130°C drying temperature; and 70% of red mud, 5% of wood chips and 25% of calciumoxide at 150°C drying temperature. In three different drying temperatures, the best ratio is 85% of red mud,5% of wood chips, 10% of calcium oxide, and the best drying temperature is 130°C. This test also providestechnical support for further industrial utilization.
