Engineering Contradiction Analysis
1Quantity of substance
If classic adsorption materials (MOFs, zeolites, amino-functionalized materials) are used for CO2 capture, then CO2 adsorption capacity is achieved, but thermal conductivity is low requiring excessive heating and cooling time and energy
Solution Approach 1:
The patent combines classic adsorption materials (MOFs, zeolites, amino-functionalized materials) with thermally conductive materials to create a composite structure. This composite approach maintains the high CO2 adsorption capacity of the classic materials while introducing thermal conductivity to reduce heating and cooling energy requirements, directly resolving the contradiction between adsorption performance and thermal efficiency
2Quantity of substance
If classic adsorption materials are used for CO2 capture, then CO2 adsorption capacity is achieved, but heating and cooling time is excessive
Solution Approach 1:
The composite structure integrates thermally conductive materials with adsorption materials, enabling faster heat transfer during heating and cooling cycles. This reduces the time required for desorption and regeneration processes while preserving the adsorption capacity, directly addressing the time loss issue
3Quantity of substance
If classic adsorption materials are used for CO2 capture, then CO2 adsorption capacity is achieved, but desorption energy requirement is high
Solution Approach 1:
The thermally conductive component in the composite material facilitates more efficient heat distribution during desorption, reducing the total energy input needed to achieve the same CO2 release. The enhanced thermal conductivity allows for more uniform and faster heating, reducing peak energy requirements
