Anthracene oil hydrogenation reaction system and method

Abstract

The invention provides anthracene oil hydrogenation reaction system and method. The reaction system comprises a micro-interface generator and a hydrogenation reactor which are connected in sequence; wherein hydrogen and anthracene oil are fed into the micro-interface generator; a hydrogenation product outlet is formed in the side wall of the hydrogenation reactor, a product discharged from the hydrogenation product outlet is introduced into a first separation tank to separate hot high-pressure separation gas and hot high-pressure separation oil, and the hot high-pressure separation gas entersa second separation tank to be separated into cold high-pressure separation gas and cold high-pressure separation oil, and the hot high-pressure separated oil enters a third separation tank to be separated into hot low-pressure separated gas and hot low-pressure separated oil, the hot low-pressure separated oil enters a cracking reaction tower to be subjected to a cracking reaction, and an obtained cracking reaction product enters a fractionating tower to be subjected to fractionation. After the reaction system provided by the invention is combined with the micro-interface generator, the energy consumption is reduced, the reaction temperature is reduced, the reaction yield is improved, the utilization rate of raw materials is improved, particularly the utilization rate of hydrogen is improved, and meanwhile, the productivity is effectively improved.

Description

technical field [0001] The invention relates to the field of hydrogenation of anthracene oil, in particular to a reaction system and method for hydrogenation of anthracene oil. Background technique [0002] Anthracene oil is a part of coal tar components. The distilled tar is cut at 280-360°C. It is generally a yellow-green oily liquid. There are crystals at room temperature. The crystals are yellow and have blue fluorescence. They are soluble in ethanol and ether. Insoluble in water, partially soluble in hot benzene, chlorobenzene and other organic solvents, with strong irritation. It is combustible when exposed to high temperature and open flame. The main components are anthracene, phenanthrene, fluorene, acenaphthene, carbazole, etc. [0003] By adopting the hydrogenation process of anthracene oil, desulfurization, unsaturated hydrocarbon saturation, denitrogenation reaction and aromatic hydrocarbon saturation can be effectively realized, thereby improving the stability ...

AI Technical Summary

Problems solved by technology

[0004] At present, most anthracene oil hydrogenation processes adopt hydrofining, hydrocracking, or a combination of the two two-stage hydrogenation processes. Although the hydrogenation process is convenient to operate and easy to industrialize, the energy consumption is high and the pressure of the hydrogenation reactor is high. High temperature, high temperature, relatively low production capacity
