Axial radial micro-catalysis reaction unit and its application

Abstract

The invention discloses an axial-radial micro-catalytic reaction unit and application thereof. The axial-radial micro-catalytic reaction unit contains a central column and a sleeve which coaxially sleeves the central column. The central column has axial micro-reaction channels which axially pass through the central column. Radial micro-reaction channels which pass through the sleeve are arranged in the radial direction of the sleeve. The axial-radial micro-catalytic reaction unit provided by the invention can be used for a reaction with reaction volume changing. In addition, use amount of a catalyst is small; pressure drop is low; retention time is short; utility rate of space is high; and there is no gas bias current or short circuit phenomenon.

Description

technical field [0001] The invention relates to an axial radial micro-catalysis reaction unit and its application. Background technique [0002] At present, there are mainly two types of fixed bed reactors, one is axial fixed bed reactor, and the other is radial fixed bed reactor. Axial reactor design, relatively easy processing, and simple operation, but there are problems with large reactor equipment, large bed pressure drop, prone to local overheating, slow heat transfer, low conversion rate, obvious amplification effect, and the need for materials for the reactor. high-level issues. The radial bed reactor has a large height-to-diameter ratio, a small bed pressure drop, and a short residence time of the reactants in the catalyst bed, but it is difficult to achieve uniform distribution of the reactants in the radial direction, and the production intensity of the unit catalyst bed is low. [0003] In order to overcome the problems of low heat transfer and mass transfer ef...

Problems solved by technology

Axial reactor design, relatively easy processing, and simple operation, but there are problems with large reactor equipment, large bed pressure drop, prone to local overheating, slow heat transfer, low conversion rate, obvious amplification effect, and the need for materials for the reactor. higher grade questions

The radial bed reactor has a large height-to-diameter ratio, a small bed pressure drop, and a short residence time of the reactants in the catalyst bed, but it is difficult to achieve uniform distribution of the reactants in the radial direction, and the production intensity of the unit catalyst bed is low

[0003] In order to overcome the problems of low heat transfer and mass transfer efficiency in traditional chemical industry, microchemical technology emerged in the 1980s and 1990s.
