Method of refining coal by short residence time partial liquefaction to produce petroleum substitutes and chemical feedstocks

摘要: This invention generally relates to short residence time decomposition and volatilization of coal produce liquid co-products, including petroleum substitutes chemical feedstocks, while minimizing production char gas without utilization external hydrogen, that is, hydrogen other than contained in the feedstock. The more particularly an improved partial liquefaction process for economically producing feedstocks from by a refining employing vaporization conservation.
