%X On the basis of experiments, this paper discusses the influence of coal size and pulp concentration upon mic-robial desulfurization of coal. Experimental results show that the smaller the coal size is, the higher the coal desulfurization rate will be. When the coal size is smaller than 0.054mm (coal pulp concentration is 10%), 44.1% of the sulfur in the coal can be removed in 12 days, thus reducing the total sulfur content of the coal from 2.55% to 1.425%. The optimum pulp concentration for coal desulfurization is 10%. Under this condition (coal size is 0.073-0.088mm), the microorganism can remove about 38.9% of the sulfur in the coal in 12 days, thus reducing the total sulfur content of the coal from 2.55% to 1.558%.
