The transient phase is significant for several reasons:
1. Optimization: During the transient phase, the system's behavior provides valuable information on the kinetics and mechanisms of the catalytic process. This data can be used to optimize reaction conditions. 2. Catalyst Stability: Understanding how a catalyst performs during the transient phase can offer insights into its stability and durability over time. 3. Scale-Up: For industrial applications, recognizing the transient behavior is essential for scaling up from laboratory to production scale.
