The frequency of updating catalysts depends on the specific process and the type of catalyst used. For example:
1. Homogeneous Catalysts: These may require frequent updates or replacements due to their solubility in the reaction medium, which can lead to loss over time. 2. Heterogeneous Catalysts: These tend to be more stable and may need updates less frequently. However, factors like coking, sintering, and poisoning can necessitate periodic regeneration or replacement. 3. Biocatalysts: Enzymes and other biological catalysts might need updates based on their shelf-life and activity retention.
