Abstract

A study was made to desulphurize the coal from WuHai of Nei Meng Gu province in China, characterized by high content of sulphur (2.85%) and high content of organic sulphur (0.49%) by using the mesophilic bac-terias isolated from WuHai coal. In the present investigation, while using these natural microbial strains, the optimum results were obtained under conditions of desulphurization was carried out when coal particle size of -6 mm and column height 1.5 meters after continuous treatment for 6 days. Maximum total sulphur concentra-tion of the desulphurized coal was 0.70%, a desulphurize rate, as high as, 70–80% of inorganic and 40-50% organic sulphur demonstrated the efficiency of using the mesophilic bacteria for desulphurization, the result showed that the ash content was reduced and the calorific value was increased due to gangue minerals dis-solved in acidic mediums.
