METHOD FOR PRODUCTION OF LIQUID PRODUCTS OF COAL Russian patent published in 1995 - IPC

Abstract RU 2041241 C1

FIELD: petrochemistry. SUBSTANCE: coal is mixed with additive and is heated. Then paste-forming agent at weight ratio 2:1-3:1 is added. Thus prepared mixture is affected by heat treatment at 250-350 C. Desired products are isolated by consequently extraction with hexanol, benzene and quinoline. The process is followed by distillation of solvent. Quinones or sulfates of transition metals are used as mentioned above additives, their quantities being 1.5-5.0 of coal mass. EFFECT: improves efficiency of the method. 2 cl
