Microbial desulphurisation of coal: a review

Abstract

During the production and processing of coal, burning it for energy production may cause a series of environmental pollution due to the amount of sulphur in it. When the consumed sulphur in coal is in the form of sulphur dioxide at the end of combustion, it reacts with water at high altitudes. Moreover, it goes down to the earth in the form of sulphuric acid, as well as damaging plants. The corrosive harmful impact on industrial plants is the removal of the sulphur in the coal when it is environmental. Microorganisms that use sulphur as food to eliminate the anxiety of clean production brought about by the chemical method. This review determined the study contains information about which microorganism is effective in removing sulphur in coal and also the types of organisms that should be according to the organic sulphur type in coal.
