Chromatium was cultured in coke oven gas (COG) and water system and coal water slurry. The desulfurization of Chromatium was also studied. These bacteria grew very well in the system of COG and water, and also well in coal water slurry. It took 80.6 hours for one generation of Chromatium in the system. The size of coal particle was more important during the process of desulfurization .The ratio of desulfurization was 53.2% when the coal particle was 200 mesh.

Underground coal gasification is one of the project in Chinese coal science and technology research. It can be used in the deep seam of decrepit coalmine, coal seam under river, building and cities, boundary coal seam and pillars and also it can reduce the production cost and increase economic benefit of enterprise. At present, the coal production was deep operation in Pingxiang Coal Industry Group Co., so the safety production condition is difficult day by day, the production cost is increased and economic benefit is decreased. Therefore, to develop the underground coal gasification project may possess very important role.
