Radial reactor

Abstract

The invention relates to a fixed bed radial catalytic converter used for a gas-solid flow decrease/enthalpy increase chemical reaction, and concretely relates to a radial catalytic converter comprising a plurality of catalyst beds and having a plurality of flow forms. The radial reactor comprises a reactor housing, a support frame arranged in the reactor housing, a central cylinder positioned above the support frame, outer ring members coaxially arranged between the central cylinder and the reactor housing, and a plurality of inner ring members coaxially arranged between the central cylinder and the outer ring members. The arrangement of the inner ring members divides the catalyst loading channel of a present reactor into at least three parts, the inner side part and the outer side part are used as catalyst loading rooms, and the middle part is used as a reactant flow channel, so the surface area of the catalyst beds is increased, the bed thickness is reduced, side reactions are reduced, the reactor resistance is reduced, and the filling amount of the catalyst is also increased in a case of a same reactor volume, thereby the production and processing capacity is increased in a case of the same reactor volume.

Description

technical field [0001] The invention relates to a fixed-bed radial catalytic reactor for gas-solid two flow reduction / enthalpy-increasing chemical reactions in petrochemical, daily chemical, chemical, fertilizer, light industry, carbon-chemical and surfactant industries, specifically A radial catalytic reactor comprising multiple catalyst beds. Background technique [0002] The fixed bed catalytic reactor is the core equipment of the above chemical reaction. The size, structure, type and working condition of the reactor determine the industrial degree, investment scale, energy consumption of the device and production cost of the above chemical reaction. Most of the existing fixed bed reactor types are axial reactor, radial reactor and axial radial reactor. [0003] The radial reactor is a high-efficiency and energy-saving gas-solid phase fixed-bed reactor in which the reactant flow passes through the catalyst bed along the diameter or radius of the reactor. Compared with ...

AI Technical Summary

Problems solved by technology

[0006] There is only one catalyst bed in the above-mentioned radial reactor, and the reactants flow in only one direction, resulting in a small contact area between the reactants and the catalyst bed, and the thickness of the bed will be reduced when the catalyst loading is ensured. Larger, thus adversely affecting the related catalytic reactions in terms of conversion rate, selectivity and side reaction occurrence rate, etc.
