The literature on microbial desulphurization of coal is reviewed so as to provide a compilation of the scattered information available on the salient features of this biogenic process. The review discusses, in turn, the types of microorganisms involved in coal desulphurization, the chemistry of the
The effect of atmospheric oxidation or weathering on different forms of sulphur in coal has been studied using a coal sample ground to ~63 pm and kept exposed to the atmosphere for up to 228 days. Occasionally, samples were taken from the exposed coal for analysis of total-, sulphate-, pyritic-and o
The rationale for magnetic demineralization of coal depends on the paramagnetism of a portion of the coal minerals, their liberation, and their capture by magnetic forces. Pyrite is especially important, being the major form of sulphur in many commercial coals. An experimental separator consisting o
Coals from Thailand were desulphurized by leaching in a small stirred autoclave with aqueous hydrogen peroxide/sulphuric acid solution. Most of the inorganic sulphur and a small portion of the organic sulphur were removed, and ash was substantially reduced. The effect of process conditions (temperat
