PROCESS FOR HYDROGENANT CHARCOAL EXTRACTION USING SUPERCRITICAL GAS SOLVENT

摘要

PROCESS FOR HYDROGENING COAL EXTRACTION USING A SUPERCRITICAL GASEOUS SOLVENT. /P P THE COAL CAN BE EXTRACTED BETWEEN 420 AND 500C AT A PRESSURE GREATER THAN 100BARS USING A GASEOUS SOLVENT CONTAINING AT LEAST 25 OF A HYDROGEN DONOR TO MAKE MAXIMUM THE EXTRACT YIELD AND MINIMUM THE COAL RESIDUE YIELD. /P P WHEN THE RESIDUE YIELD IS LESS THAN 50, ANY OF THIS RESIDUE CAN BE USED ON PLACE TO PROVIDE ENERGY, HYDROGEN, ETC. THE LIQUID CHEMICALS OBTAINED BY THE EXTRACTION CAN BE USED AS A RAW MATERIAL FOR THE CHEMICAL INDUSTRY OR AS A LIQUID FUEL.
