Several challenges need to be addressed to improve catalyst delivery, including:
Catalyst Deactivation: Over time, catalysts can lose their activity due to poisoning, sintering, or fouling. Effective delivery systems must account for and mitigate these issues. Mass Transfer Limitations: In heterogeneous catalysis, the diffusion of reactants to the catalyst surface can be a limiting factor. Enhancing mass transfer can improve delivery efficiency. Environmental and Safety Concerns: Delivery systems must be designed to minimize environmental impact and ensure safe handling and disposal of catalysts.
