Information of the distribution of the organic sulphur forms in coals is needed to improve our current understanding of emerging chemical and biological desulphurization processes and of devolatilization and liquefaction behaviour. This project has therefore investigated X-ray and reductive techniques for the speciation of organic sulphur forms in coals. Research has been carried out to improve the differentiation of thiophenic and non-thiophenic sulphur forms in X-ray techniques by using selective oxidization to convert the non-thiophenic forms into sulphoxides and sulphones, to optimise atmospheric pressure (AP) and high pressure temperature programmed reduction (TPR) techniques for the speciation of organic sulphur forms in coal and coal derivatives, and to correlate the results from the TPR and X-ray absorption techniques to provide an extensive library on the distribution of organic sulphur forms in coals and coal derivatives.
