METHOD FOR HYDROGENATED COAL LIQUEFACTION

摘要

Method for hydrogenating coal liquefaction. Rubbing oils and hydrogen-containing circulation gas are used, as well as supplementary fresh hydrogen, at pressures above 100 bar and temperatures between about 300.degree. and 550.degree.C in a liquefaction reactor. An amount of circulation gas from 4,000 to 8,000m3 under normal conditions per ton ofentry coal is conducted together with the initial mixture of crushed coal, rubbing oil and supplementary fresh hydrogen through the entire liquefaction reactor.
