Solution Overview
Problem
There is an urgent need to reduce atmospheric carbon dioxide emissions and develop methods to incorporate CO2 into useful products effectively, as existing technologies are inadequate in addressing environmental carbon dioxide removal and utilization.
Innovation Solution
A method involving the treatment of materials, particularly fibrous materials, by sequentially or simultaneously contacting them with a composition containing an amino compound and carbon dioxide or its source, which can result in CO2 being bound to the material's surface in a reversible or irreversible manner, enhancing environmental profiles and potential applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If existing technologies are used to remove carbon dioxide from the atmosphere, then carbon dioxide removal can be achieved, but the methods are inadequate in effectively incorporating CO2 into useful products
Solution Approach 1:
The patent introduces an amino compound as an intermediary substance that mediates between carbon dioxide and fibrous materials. The amino compound first contacts the fibrous material to modify its surface, then contacts carbon dioxide to enable binding. This two-step intermediary approach allows CO2 to be effectively incorporated into useful fibrous products while achieving removal from the atmosphere.
Solution Approach 2:
The patent utilizes parameter changes in the amino compound's chemical state to facilitate CO2 binding. The amino compound is applied in a specific chemical form to the fibrous material, then undergoes transformation when contacting CO2, enabling the material to capture and retain carbon dioxide in a stable bound state.
2Reliability
If the surface of material is contacted with amino compound and carbon dioxide, then carbon dioxide can be bound to the surface in reversible or irreversible manner, but the process requires sequential or simultaneous treatment steps
Solution Approach 1:
The patent applies preliminary action by first contacting the fibrous material surface with the amino compound before exposing it to carbon dioxide. This pre-modification of the surface with the amino compound prepares the material to effectively bind CO2, ensuring reliable and stable binding while structuring the process in manageable sequential steps.
3Object-affected harmful factors
If natural fibres are used as material, then environmental profile is improved, but the material requires surface modification to effectively capture carbon dioxide
Solution Approach 1:
The patent applies local quality by modifying only the surface of the natural fibrous material rather than the bulk material. The amino compound is applied to the surface where it contacts CO2, leaving the internal structure of the natural fibres intact. This approach maintains the environmental benefits of natural fibres while adding the necessary surface functionality for CO2 capture.
