Hydrogenation reaction device and hydrogenation reaction method for producing hydrogen peroxide through fluidized bed

Abstract

The invention relates to a hydrogenation reaction device and hydrogenation reaction method for producing hydrogen peroxide through a fluidized bed. The hydrogenation reaction device comprises a hydrogenation reaction kettle, wherein a hydrogenation kettle working liquid distribution pipe is arranged at the bottom of the hydrogenation reaction kettle; an inlet of the hydrogenation kettle working liquid distribution pipe is connected with a hydrogenation kettle working liquid inlet pipe; a hydrogen distribution device is arranged below the hydrogenation kettle working liquid distribution pipe; a main inlet of the hydrogen distribution device is connected with a fresh hydrogen supply pipe; the top of the hydrogenation reaction kettle is connected with a catalyst addition pipe; the upper end of the catalyst addition pipe is connected with an outlet of a catalyst addition tank through a catalyst addition valve; a hydrogenation kettle gas phase outlet is formed in the center of the top of the hydrogenation reaction kettle; and at least two reaction kettle outlets are uniformly formed in the middle circumference of the hydrogenation reaction kettle. The remaining hydrogen after reaction is condensed through a hydrogen condenser and compressed through a hydrogen circulating compressor, and returns to the hydrogenation reaction kettle from a hydrogen circulating pipe; and a catalyst in a hydrogenated liquid is separated and refluxed through a catalyst preseparator, is filtered and backwashed through a catalyst filter and then returns to the hydrogenation reaction kettle. The hydrogenation reaction device is low in manufacturing cost and unit consumption of a product and high in production efficiency.

Description

technical field [0001] The invention relates to a hydrogenation reaction device for producing hydrogen peroxide in a fluidized bed, and also relates to a hydrogenation reaction method for producing hydrogen peroxide in a fluidized bed, belonging to the technical field of hydrogen peroxide manufacturing equipment. Background technique [0002] Hydrogen peroxide is an important inorganic chemical raw material, widely used in papermaking, textile, medicine, chemical industry, electronics, environmental protection and other fields. Hydrogen peroxide decomposes to produce water and oxygen, which has no secondary pollution to the environment and conforms to the concept of green product production. [0003] In the prior art, hydrogen peroxide is usually produced by the anthraquinone method. The anthraquinone method uses 2-ethylanthraquinone as a carrier and palladium as a catalyst to directly synthesize hydrogen peroxide from hydrogen and oxygen, followed by hydrogenation. , oxida...
