Title: PROCESSES FOR DESULFURIZING COAL
Abstract:
A method of removing organic sulfur from coal in which the coal is dispersed in perchloroethylene in the presence of a catalyst which is effective to disrupt C-S bonds and thereby liberate sulfur species from the coal. The processed coal is recovered, and the perchloroethylene is separated from the liberated sulfur species and recycled.
