Coal liquefaction reactor and coal liquefaction production system

Abstract

The invention provides a coal liquefaction reactor and a coal liquefaction production system. The coal liquefaction reactor comprises a reactor barrel, a slurry distributor and a gas distributor, wherein the reactor barrel is used for containing reaction liquid and ensuring that the reaction liquid has a preset reaction liquid level; the slurry distributor is arranged in the reactor barrel and positioned below the reaction liquid level in the reactor barrel; the gas distributor is arranged in the reactor barrel and positioned between the slurry distributor and the bottom of the reactor barrel. The technical scheme can solves the problems in the prior art that the existing coal liquefaction reactor cannot meet the requirement that the standing time of light liquefaction products in the liquefaction reactor is short during coal liquefaction and the standing time of coal difficult to liquefy and heavy liquefaction products in the liquefaction reactor is long.

Description

technical field [0001] The invention relates to the field of coal chemical industry, in particular to a coal liquefaction reactor and a coal liquefaction production system. Background technique [0002] Coal direct liquefaction (that is, coal liquefaction) is a process in which coal is hydrogenated and reacted under the combined action of a certain temperature (about 450 ° C), a certain pressure, and a catalyst. It is the process of producing liquid fuel (that is, petroleum) substitutes and coal One of the important methods of base materials is one of the directions of high-efficiency and clean utilization technology of coal. After a century of research and development, the direct coal liquefaction technology has basically matured. [0003] The coal liquefaction reactor is one of the most critical equipment in the direct coal liquefaction process, and the form of the coal liquefaction reactor largely determines the characteristics of the coal liquefaction process. At prese...

AI Technical Summary

Problems solved by technology

[0004] The main purpose of the present invention is to provide a coal liquefaction reactor and a coal liquefaction production system to solve the problem that the existing coal liquefaction reactor in the prior art cannot satisfy the residence time of light liquefied products in the coal liquefaction process. Shorter requirements, and the inability to meet the requirements of difficult-to-liquefy coal and heavy coal liquefaction products staying in the liquefaction reactor for a longer period of time
