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

Abstract

PURPOSE: To make it possible to easily and simply separate an insoluble component in a short period of time, to economically prepare a low-ash modified coal and to utilize a high-ash coal as a heat source or a hydrogen source for the process, by separating a coal solution into a low-ash stream and a high-ash stream.
CONSTITUTION: A slurry composed of coal 1 and liquefaction solvent 2, is preheated in preheater 200 together with hydrogen gas 3, and admitted to reactor 210, where it is hydrocracked at a pressure ≥30atm, at a temperature of 350W500°C. The vapor-liquid mixture obtained is separated in separator (a), gas 4 being recycled and used after separated from methane, etc. in refining apparatus 400. On the other hand a coal solution is introduced to separator (b), where it is separated into a high-ash stream 7 and a low-ash stream 6. Light oil 9, a modified coal of ash content ≤2%, and liquefaction solvent 11, are recovered by the distillation of said low-ash stream, and a light oil 12, higher-ash modified coal 13 and liquefaction solvent 14 are recovered from said high-ash stream 7, in solvent recovery plant 310. The modifid coal 13 is gasified. A part of the gas obtained is used for the production of hydrogen and the balance is used as a fuel.
