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
The effect of air, steam and hydrogen on the desulphurization of 10 U.S. high-volatile bituminous coals was investigated. Air treatment was most effective at 450ยฐC where an average of 38% total sulphur, comprising 51% of the inorganic sulphur and 20% of the organic sulphur, was removed. With steam a
