Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional catalytic materials containing Ni and oxidic components (Zr, Si) are used for hydrogenation reactions, then the catalytic material can be prepared through standard precipitation and reduction processes, but the catalytic activity and selectivity towards desired amine group-containing compounds are insufficient, leading to increased by-product formation
Solution Approach 1:
The invention changes the chemical composition parameters of the catalytic material by introducing specific additional metals (Pd, Pt, Rh, Ir, Ru, Os, or Re) in controlled amounts (0.01-10 wt%) alongside Ni (50-95 wt%). This parameter modification transforms the catalytic properties, enhancing both activity and selectivity while reducing harmful by-product formation during hydrogenation reactions
Solution Approach 2:
The invention creates a composite catalytic material by combining Ni with one or more additional metals (Pd, Pt, Rh, Ir, Ru, Os, or Re) on an oxidic support containing Zr and Si. This composite structure leverages the synergistic effects of different metals to achieve superior catalytic performance compared to conventional single-metal or simple alloy catalysts
2Duration of action of stationary object
If conventional catalytic materials are used in hydrogenation reactions, then the reaction can proceed with standard catalysts, but the longevity and stability of the catalyst is insufficient, requiring frequent replacement or regeneration
Solution Approach 1:
The invention modifies the compositional parameters by incorporating specific additional metals (Pd, Pt, Rh, Ir, Ru, Os, or Re) in optimized amounts (0.01-10 wt%) with Ni (50-95 wt%). This parameter change enhances the thermal and chemical stability of the catalyst, thereby extending its operational longevity and maintaining reliability over extended reaction periods
Solution Approach 2:
The composite structure combining Ni with noble or precious metals (Pd, Pt, Rh, Ir, Ru, Os, or Re) on a stable oxidic support (Zr and Si oxides) creates a more robust catalyst system. The composite material resists deactivation mechanisms better than conventional catalysts, extending service life and maintaining stability
3Manufacturing precision
If conventional catalytic materials with Ni and oxidic support are used, then the catalyst can be prepared by standard precipitation methods, but the catalytic selectivity towards desired products is low, resulting in significant by-product formation
Solution Approach 1:
The invention precisely adjusts the compositional parameters by incorporating specific additional metals (Pd, Pt, Rh, Ir, Ru, Os, or Re) in controlled amounts (0.01-10 wt%) alongside Ni (50-95 wt%). This precise parameter control enables high selectivity towards desired amine group-containing compounds, minimizing by-product formation during hydrogenation reactions
Solution Approach 2:
The composite catalytic material combining Ni with selective metals (Pd, Pt, Rh, Ir, Ru, Os, or Re) on an oxidic support creates active sites with enhanced selectivity. The composite structure promotes selective hydrogenation pathways while suppressing side reactions, significantly reducing by-product formation
