Embodiment 1

[0062] A super-large hydrogenation reaction unit with an annual output of 5 million tons of oil, with a daily coal processing capacity of 42,000 tons, a reactor inner diameter of 6500 mm, an entrained flow bed height of 48 m, and a bubbling bed height of 40 m, totaling a total height of 98 m.

[0063] Adopt the nozzle described in the patent ZL95111750.5, with a single row of nozzles, a total of 8, the distance H between the horizontal plane of the nozzle 2 and the upper nozzle chamber on the air flow bed is 6500mm;

[0064] In the pulping unit, coal is mixed with circulating solvent and catalyst (the amount of catalyst is 1-5% of the weight of coal), and the solid particle size of the product is ≯200μm, and the weight concentration of coal slurry is 50%. After sieving, it is pumped to the hydrogenation reaction device , enter the hydrogenation reaction device through the second channel 202 of the nozzle 2, hydrogen (total flow is 1400000Nm 3 / h) Enter the hydrogenation reaction...

Abstract

The invention discloses coal hydrogenation reacting device and its industry application. The reacting device includes air flow bed, bubbling bed, coal slurry circulating pump, and heat exchanger. The air flow bed and bubbling bed are set in the shell body of the same cylindrical form internal lining refractory materials. And the former is at the above. The latter is at the under. The device and method can be used in direct liquefaction with 5 million ton oil product per year, 40 thousand ton coal processing quantity per day, increase H2 transmission rate to prevent coal slurry precipitation, has convenient operation control, realize slurry pulverization and the mixture of the fog drop and H2 by nozzle itself crossing jet and the impacting flow formed by the opposed nozzle.

Description

technical field [0001] The invention relates to a coal direct liquefaction reaction device and its application. Background technique [0002] Coal direct liquefaction is one of the coal-to-oil technologies. The German Ruhr Coal Company (Kohleoel), the Japanese New Energy Industry Technology Development Organization (NEDOL), the American HRI Company, and EXXON Company have all carried out a lot of research and development work. Domestic Shenhua Group Co., Ltd. (on coal direct liquefaction process, ZL200410070249.6), Coal Research Institute Beijing Coal Chemical Research Branch (on coal direct liquefaction reactor, ZL03102672.9) and Shanxi Institute of Coal Chemistry, Chinese Academy of Sciences (on Coal direct liquefaction catalyst, ZL98102883.7) and other units have also conducted research in this field. In view of economic and technical reasons, large-scale industrial production cannot be realized at present, and it cannot meet the annual production of ≥ 5 million tons of o...
