How Does Physical Pretreatment Affect Catalyst Performance?
Physical pretreatment can have a profound impact on the performance of catalysts in several ways:
Surface Area and Porosity Increasing the surface area and porosity of the catalyst through methods like milling and calcination provides more active sites for the reaction to occur. This enhances the overall activity of the catalyst.
Structural Stability Thermal treatments such as calcination and annealing can improve the structural stability of the catalyst, making it more resistant to deactivation and sintering under reaction conditions.
Dispersion of Active Components Mechanical activation and pre-shaping can help in the uniform dispersion of active components on the catalyst surface. This ensures that the active sites are evenly distributed, leading to better catalytic performance.
Mechanical Strength Pre-shaping techniques can enhance the mechanical strength of the catalyst, making it more durable and less prone to attrition during the reaction process.
