Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing selectively permeable membrane type reactors face efficiency issues due to the catalyst and membrane being disposed in the same space, leading to reduced catalytic reaction and selective permeation efficiency, with catalyst powder adhering to the membrane and causing deterioration.
Innovation Solution
A novel reactor design featuring a carrier with partitioned cells, where the catalyst is disposed in some cells and the selectively permeable membrane in others, preventing catalyst powder from adhering to the membrane and maintaining membrane functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the catalyst and selectively permeable membrane are disposed in the same space, then the reactor structure is simplified, but the catalytic reaction efficiency and selective permeation efficiency are reduced
Solution Approach 1:
The reactor is divided into multiple cells (first cell, second cell, third cell) with distinct functions. The catalyst is disposed in the first cell, the selectively permeable membrane in the second cell, and the partition wall between them enables product transfer. This segmentation allows each component to operate optimally without interference, resolving the contradiction between structural simplicity and reaction efficiency.
2Device complexity
If the catalyst and selectively permeable membrane are disposed in the same space, then the reactor structure is simplified, but the membrane deteriorates due to catalyst powder adhesion
Solution Approach 1:
By separating the catalyst-containing first cell from the membrane-containing second cell using a partition wall, the invention prevents direct contact between catalyst powder and the membrane. This eliminates the adhesion and deterioration problems while maintaining a relatively simple integrated reactor structure.
Solution Approach 2:
The partition wall acts as an intermediary structure that enables product transfer from the first cell to the second cell while preventing direct contact between the catalyst and membrane. This mediator resolves the contradiction by allowing functional interaction without physical contamination.
3Productivity
If the catalyst powder adheres to the membrane, then the membrane surface is blocked, but the separation efficiency is reduced
Solution Approach 1:
The physical separation of catalyst and membrane into different cells prevents catalyst powder from reaching and blocking the membrane surface. This maintains high separation efficiency by eliminating the adhesion problem at its source.
Solution Approach 2:
The partition wall serves as a protective barrier that allows reaction products to pass through while blocking catalyst powder from reaching the membrane. This intermediary structure prevents harmful adhesion while maintaining beneficial product separation.

AI summary
A selectively permeable membrane type reactor including a catalyst for promoting a chemical reaction, a selectively permeable membrane which selectively allows a specific component to pass therethrough, and a carrier for disposing the catalyst and the selectively permeable membrane the carrier being a tubular body having two or more gas passage cells partitioned and formed by a partition wall formed of a porous body, the catalyst being individually disposed in some of the cells of the carrier, the selectively permeable membrane being individually disposed in the remainder of the cells, and the cell in which the catalyst is disposed and the cell in which the selectively permeable membrane is disposed being adjacently disposed with the partition wall positioned therebetween.
