The shape of a catalyst affects multiple aspects of its performance:
Surface Area: Different shapes offer varying surface areas, which directly impact the number of active sites available for reactions. Pore Structure: Shapes with intricate pore structures can enhance mass transfer and accessibility of reactants to active sites. Pressure Drop: Shapes like spheres and monoliths minimize pressure drop, which is crucial for efficient reactor operation. Mechanical Strength: Certain shapes like rings and pellets offer higher mechanical strength, making them more durable under high-pressure conditions.
