Axial micro-catalytic reaction unit and application thereof

Abstract

The invention discloses an axial micro-catalytic reaction unit and application thereof. The axial micro-catalytic reaction unit is characterized in that the axial micro-catalytic reaction unit comprises a column and micro-reaction channels axially penetrating the column; the place above the column is communicated with a fluid below the column only through the micro-reaction channels; and the the micro-reaction channels are provided with upper micro-reaction channel openings and lower micro-reaction channel openings with different diameters. The axial micro-catalytic reaction unit provided by the invention can be applied to reactions with changes in reaction volume, enables the usage amount of a catalyst to be small, and is low in pressure drop, short in retention time, high in space utilization rate and free of the phenomena of bias current and short circuit of gas.

Description

technical field [0001] The invention relates to an axial 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.

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.
