Abstract: By orthodox experiment, the main influence factors of desulfurization by sulfolobasof pH value, temperature, coal slurry concentration and coal granularity are studied in detail and the optimal experimental conditions were also obtained. The experimental results demonstrate thatsulfolobasbeing kind of linking-heat, acidophilic and self-supported bacterium with double characters can effectively remove inorganic and organic sulfur in coal. The superlatively desulfurization rate is up to 48.57% total sulfur and 41.71% inorganic sulfur within 10 d and its desulfurization rate can be greatly affected by the four factors above mentioned. Therefore, the optimum conditions of desulfurization are obtained by comprehensive experiment and they are as following: pH value 3, temperature 70℃, coal slurry concentration 10% and coal granularity 150μm, respectively. Moreover, the repetition experimental results confirm that the desulfurization bysulfolobasis steady.
