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

摘要

Coatings for coal is mixed with a non- hydrogen -donating solvents and coatings raw coal , the raw material coal an extraction step of extracting the soluble components in the non- hydrogen -donating solvent , a raw material that can be dissolved in the non- hydrogen -donating solvent contained in the extract was separated by the method having the solid-liquid separation step of separating the extract after the extraction process extract glass minutes consists of a coal component. By coating these coatings to obtain a modified coal coal .
