Catalyst distillation component and catalyst distillation method used said component

Abstract

The invention discloses a kind of catalyst distillation module and uses this module the catalyst distillation method.The invention catalyst distillation module includes the granules of catalyst, the silk screen vessel and the filler plate, its characteristic lies in, in the stated silk screen vessel which is used to load and fill granules of catalyst one by one or interval lays to the stated free channel which is formed by fold put the filler plate;Among them the stated filler plate is the corrugated sheet padding,open arbitrary shape holes on the corrugated sheet trough,remove the open hole part on the stated corrugated sheet, or divides the hole opened part into two parts along the ripple direction, then move upward or downward the formed two teeth pieces.The invention module has the force fluid redistribute ability, overcame the flaw that channel and so on cause the mass transfer effect droppes ; Lengthenes the fluid mobile way, increases the hold liquid volume of the reaction zone liquid.

Description

technical field [0001] The present invention relates to a kind of equipment and method of chemical engineering and catalytic reaction engineering, especially to a new component of catalytic distillation tower and its application in gas-liquid, liquid-solid, liquid-liquid-solid, gas-liquid-solid Methods in Catalytic Distillation Reactions. Background technique [0002] In the fields of chemical industry, petrochemical industry, fine chemical industry, metallurgy and environmental engineering, there are many gas-liquid, liquid-solid, liquid-liquid-solid, gas - Liquid-solid systems. These catalytic reaction systems are particularly suitable for carrying out by means of catalytic distillation. [0003] Catalytic distillation technology is a chemical engineering and catalytic reaction engineering technology developed in recent years. It combines catalytic reaction process and distillation refining technology, and simultaneously completes catalytic reaction process and distillat...

AI Technical Summary

Problems solved by technology

The disadvantage of this component is: the catalyst is solid, so the particle size should not be too large, otherwise the catalyst cannot be fully utilized, but the catalyst particle size is too small and it is easy to be stratified with the filler, which impairs the synergistic function of the component to perform its catalytic reaction-distillation separation , In addition, this component is also prone to channeling in the bed, which affects its mass transfer and reaction effects

This kind of component has high mass transfer efficiency, good catalyst utilization rate and good product selectivity, but it has high requirements on the strength of the catalyst and high requirements on the production technology of the catalyst and packing. During the operation, the catalyst and packing are easy to separate, thus Causes large local resistance and affects the flux of gas and liquid
