  • Production Of Liquid Hydrocarbon Mixture For Refining Petroleum (AREA)

Abstract

PURPOSE: To enhance solvent performance and safety characteristic as well as to carry out reaction efficiently by a method wherein a medium b.p. component obtained from a coal liquefaction product is subjected to hydrogenation treatment and, thereafter, mixed with a low b.p. component and the obtained mixture is mixed with a high b.p. component in a specific ratio to form a liquefaction solvent.
CONSTITUTION: After coal 6 and a solvent 7 are mixed under stirring in a stirring tank 1 to form a slurry, this slurry is sent to a heating furnace 2 and heated to a predetermined temp. The high-temp. slurry is supplied to a dissolving tank 3 to complete liquefaction reaction thereof and the gas generated is discharged from the top of the dissolving tank and separated. The reaction product enters a distillation tower 4 and is herein, separated into naphtha with b.p. of 200°C or less, an component A with b.p. of 200W210°C, a component B with b.p. 211W230°C and a component C with b.p. of 231°C or more. The total amount of the component B is charged along with H2 gas 8 into a succeeding hdyrogenatin tower 5 and subjected to hydrogenation treatment. Then, the component B issued from the hydrogenation tower 5 is mixed with total amount of a part of the component A and, 50% or less of the component C is mixed with 50% or more of this mixture and the obtained mixture is circulated and used as a solvent 7 for liquefaction of coal.
