COATING MATERIAL FOR COAL, MODIFIED COAL, PROCESS FOR THE PRODUCTION OF COATING MATERIAL FOR COAL, AND PROCESS FOR PRODUCTION OF MODIFIED COAL

摘要

A coating material for coal consisting of components of raw coal for coating material which are soluble in a non-proton-donating solvent, which components are contained in an extract obtained by a process comprising the extraction step of mixing the raw coal with a non-proton-donating solvent and extracting soluble components of the raw coal into the solvent and the solid-liquid separation step of separating an extract from an extraction residue. Modified coal can be obtained by applying the coating material to coal.
