1. Preparation: The catalyst is prepared and pre-treated according to specific requirements. 2. Reactor Setup: The catalyst is loaded into a reactor, and the reaction conditions (temperature, pressure, flow rates) are set. 3. Continuous Operation: The reaction is run continuously for a specified period, often ranging from hours to several weeks or even months. 4. Monitoring: Key parameters such as conversion rates, selectivity, and yield are monitored regularly. 5. Data Analysis: The collected data is analyzed to determine the catalyst's performance over time.
