Several challenges can arise during reaction tests:
- Deactivation of Catalysts: Catalysts can lose their activity over time due to sintering, poisoning, or fouling. It is essential to identify the cause of deactivation to improve catalyst design.
- Reproducibility: Ensuring that the reaction conditions are precisely reproducible is critical for obtaining consistent and reliable results.
- Scale-up Issues: Results obtained at the laboratory scale may not always translate directly to industrial-scale processes. It is essential to consider scale-up factors during the testing phase.
