Bench scale tests are crucial for several reasons: 1. Cost-Effectiveness: They provide a low-cost method to test multiple catalysts and reaction conditions. 2. Risk Mitigation: Identifying potential issues at a smaller scale reduces risks associated with scaling up. 3. Optimization: Parameters such as temperature, pressure, and reactant concentration can be finely tuned. 4. Data Collection: They generate valuable data for kinetic modeling and process simulation.
