Process for removing sulfur from coal

摘要

A process for reducing the sulfur content of coal comprising the steps of: (1) contacting coal particles with (i) a silicate selected from the group consisting of alkali metal silicates, alkaline earth metal silicates and mixtures thereof, and (ii) a promoter material capable of oxidizing or reducing equilibrium sulfur reaction products formed by the contacting to non-equilibrium reaction products in an aqueous medium to reduce the sulfur content of coal; and (2) recovering coal particles of reduced sulfur content.
