What Strategies Are Employed for Impurity Control?
Multiple strategies can be employed to control impurities in catalytic systems:
1. Raw Material Purification: Ensuring the purity of raw materials before they enter the catalytic system can significantly reduce the introduction of impurities. 2. Process Optimization: Adjusting reaction conditions such as temperature, pressure, and pH can help minimize the formation of unwanted by-products. 3. Catalyst Regeneration: Over time, catalysts may become fouled with impurities. Regeneration techniques like calcination, reduction, or washing can restore their activity. 4. Additives: Certain additives can be introduced to the reaction to scavenge impurities or decompose them into non-interfering products.
