| abstract | UNITED STATES PATENT APPLICATION OF : LESTER E. BURGESS, KARL M. FOX, PHILLIP E. MCGARRY and DAVID E. HERMAN FOR: IMPROVED PROCESS FOR BENEFICIATING COAL ABSTRACT OF THE DISCLOSURE Beneficiated coal and a process for beneficiating coal are provided. Mined coal is pulverized in the presence of water to form a particulate coal aqueous stream. The extended surfaces of the particulate coal are rendered hydrophobic and oilophilic (oil loving) in a chemical graft polymerization reaction wherein a polymerizable organic monomer is utilized to render the parti-culate coal hydrophobic and oilophilic. The reaction occurs in an aqueous medium in the presence of free radical polymeric cata-lysts and initiators and a fuel oil. Mineral ash and sulfur normally present in the coal are separated from the treated coal in a water washing step. The un-wanted impurities are removed in a water stream. The chemical treatment and the washing step can be effected in a unitary operation. The recovered coal particles can be dried to remove excess water. Such drying can be effected using simple mechani-cal dryers. The beneficiated particulate coal can be burned as a fuel, or it can be admixed with oil to form a coal-oil mixture. A salt forming compound and a chemical treatment step are pro-vided to stabilize the coal-oil mixture. The resultant coal-oil mixture is beneficiated and stable for extended periods of time. |
