Reaction Analysis for Hydrotreatment of Coal-derived liquid by GC/MS-chromatograms

Abstract

Coal liquefaction solvents before and after hydrotreatment were analyzed by a capillary GC/MS, and the conversions of some polar compounds were determined by comparing the corresponding single ion chromatograms. The conversion of the polar fraction was estimated by the conversion of the individual polar compound obtained above. The separation of the polar fraction followed by GC/MS-chromatograms analyses enabled the determination of the conversions of many polar components during the hydrotreatment of the coal liquefaction solvent.
