Title:
COAL LIQUEFACTION
Document Type and Number:
Japanese Patent JPS5827784
Kind Code:
A
Abstract:
Coal is contacted with hydrogen and a process- derived first stage liquefaction solvent 12 in a thermal liquefaction zone to produce in effluent 14 from which a pumpable stream 25 of insoluble material which includes 850 DEG F+ liquid is separated prior to second stage hydroliquefaction at 52 to produce an effluent 55 from which 850 DEG F+ liquid 58 is recovered. The first stage liquefaction solvent includes a portion 31 of the pumpable stream 25 which contains 850 DEG F+ liquid and a portion of 59 of the 850 DEG F+ liquid 58 and comprises 15-50% of 850 DEG F+ liquid, 50-20% of insoluble material and at least 45% of 850 DEG F- liquid having an initial boiling point of at least 500 DEG F.
