Organic Desulfurization of Assam Coal and Its sulfur-rich lithotypes by sequential solvent extraction to obtain cleaner fuel

摘要

In this paper the distribution of sulfur in different lithotypes in assam coal is reported and an attempt is made for organic desulfurization of assam coal by directly using original run-of-mine coal as well as by taking its sulfur-rich lithotypes, using sequential solvent extraction to obtain cleaner fuel. More than 80/100 organic sulfur was found to have been removed by this treatment.
