PROCESS FOR CHARACTER LIQUEFACTION WITH RECYCLING CONTROL OF INSOLUBLES IN ETHYL ACETATE

摘要

THE INVENTION RELATES TO THE LIQUEFACTION OF COAL. /P P IT RELATES TO A PROCESS FOR INCREASING THE RATE OF TRANSFORMATION OF COAL INTO PRODUCTS SOLUBLE IN ETHYL ACETATE IN THE LIQUEFACTION OF COAL BY HEATING A SUSPENSION OF A SOLVENT AND CHARCOAL PARTICLES TO OBTAIN A SUSPENSION CONTAINING SOLUBLE LIQUID COMPONENTS AND COMPONENTS INSOLUBLE IN ETHYL ACETATE, CONTACT OF PART OF THE SUSPENSION WITH HYDROGEN, PARTITION OF COMPONENTS INSOLUBLE IN TWO FRACTIONS RICH AND POOR IN SOLID MATERIALS, THE LATTER CONTAINING MATERIALS INSOLUBLE IN ETHYL ACETATE ENRICHED IN ORGANIC COMPONENTS, AND RECYCLING PART OF THE LOW FRACTION IN THE DISSOLUTION ZONE IN THE DISSOLUTION ZONE 20 CONTAINING INSOLUBLES ETHYL ACETATE IN AN QUANTITY 1 SUFFICIENT TO RAISE THE TRANSFORMATION RATE OF THE COAL INTO THE SAID SOLUBLE COMPONENTS 2 INSUFFICIENT FOR THE CATALYST'S CLAMING SPEED EXCEEDS 0.3CH. / P P APPLICATION, ESPECIALLY TO LIQUEFACTION OF POOR COALS SUCH AS SUB-BITUMINOUS COAL, LIGNITE, ETC.
