Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing processes for recycling fiber cloth are time-consuming due to the need for separate catalysts for decolorization and degradation, and the subsequent separation of these catalysts, which hinders continuous treatment.
Innovation Solution
An ionic liquid catalyst is developed, where a carrier containing nickel ferrite is modified with a decolorant grafted onto nickel atoms and a degradation agent grafted onto iron atoms, enhancing decolorizing and degrading effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If separate catalysts are used for decolorization and degradation, then the specific decolorizing and degrading functions are achieved, but the process becomes time-consuming and complex due to multiple catalyst addition and separation steps
Solution Approach 1:
The patent combines decolorization and degradation functions into a single catalyst system by grafting different functional agents onto a carrier: decolorant is grafted onto nickel atoms while degradation agent is grafted onto iron atoms of the nickel ferrite carrier, enabling dual functionality in one catalyst
Solution Approach 2:
The nickel ferrite carrier serves as a universal support structure that can simultaneously host both decolorant and degradation agent, making the catalyst system multi-functional and capable of performing both decolorization and degradation reactions
2Reliability
If multiple catalysts are used for decolorization and degradation, then the specific functions are achieved, but the separation process becomes complicated and time-consuming
Solution Approach 1:
By merging decolorant and degradation agent onto the same nickel ferrite carrier, the patent ensures that both functions are integrated in a single catalyst that can be added once and removed once, eliminating the need for multiple separation steps
3Reliability
If conventional extraction methods are used for dye removal, then the extraction effect can be enhanced by selecting specific solvents, but the process remains time-consuming and requires subsequent purification steps
Solution Approach 1:
The patent replaces conventional mechanical extraction methods with a catalytic approach where decolorant grafted on nickel atoms directly decomposes dye molecules, transforming a physical extraction process into a chemical decomposition process that is more efficient and integrated
