Coal desulfurization prior to usage is a preprocessing in order to achieve clean fuel and reduce . being the solution for obtaining clean demineralized and desulfurized coal which involves solubilization of inorganic constituents in various solvents 6. . The type of reagent depends upon the type of sulfur in coal 2 and 10. .

Solubilization Of Coal With Hydrogen Sulfide And Carbon

There is a need for efficient and economical reagents for the hydrogenation and solubilization of coal and conversion of coal tar as above. In accordance with this invention the solubilization of coal and conversion of coal tar to products of lower molecular weight effected in liquid or fused reaction medium using a hydrogenation reactant .

Solubilization Of Coal Springerlink

Solubilization conceptually consists of using a solvent and sometimes a catalyst to break up the coal structure into fragments that can be dissolved by the solvent and stabilization of those fragments in a solution. Solubilization can be used to facilitate chemical structure studies or it may be the first stage of a coal liquefaction process.
