Because of the direct combustion, the sulphur contained in many of the world's coals provides serious environmental pollution problems. Since existing processes of coal desulphurization are not very satisfactory, microbial desulphurization seems one of most promising methods for the industrial profit of high sulphur content coals. Several aerobic strains of bacteria can play an important role in the removal process. So, some mesophilic-Thiobacillus ferrooxidans, Thibacillus thiooxidans- and some thermophilic-Sulfolobus acidocaldarius, Thermophilic thiobacilli- microorganisms are capable of oxidizing reduced sulphur compounds. Moreover, Sulfolobus acidocaldarius can oxidize also some of the organic sulphur compounds from coal. This research has undertaken a deep study on the basis of microbiological desulphurization, useful microorganisms and, above all, about the parameters involved in the mentioned process, optimizing them so that the maximum values of velocity and desulphurization rate are obtained. We can conclude that microbiological methods have a high potential in remeving organiz and inorganic sulphur compounds from coal. Homever, further improvements in sulphur removal rate would be essential to develop an economically feasible process. ABSTRACT. INTRODUCTION. DESCRIPTION OF THE METHOD.
