Lab scale testing in catalysis can encounter several challenges:
Reproducibility: Ensuring consistent results across multiple tests can be difficult due to variations in experimental conditions. Scale-up Issues: Catalysts that perform well at lab scale may not always translate to industrial scale due to differences in reaction dynamics. Deactivation: Catalysts may lose activity over time due to factors like poisoning, sintering, or coking. Cost: High costs associated with catalyst materials and sophisticated analytical equipment can be a barrier.
