What Are the Key Factors Affecting Catalysis in Ethylene Oxide Production?
Several factors influence the effectiveness of the catalyst:
1. Temperature: The optimal temperature range for the reaction is typically between 200-300°C. Higher temperatures can increase the rate of reaction but may also lead to more by-products. 2. Pressure: Operating at higher pressures can enhance the conversion rates but must be balanced against safety considerations. 3. Oxygen to Ethylene Ratio: The ratio of oxygen to ethylene must be carefully controlled to maximize yield and minimize side reactions. 4. Catalyst Composition: The purity and surface area of the silver catalyst are crucial for its performance.
