What types of mechanical strength tests are commonly used?
Several mechanical strength tests are widely used to evaluate the robustness of catalysts. These include:
Crush strength test: Measures the force required to break individual catalyst particles. This is especially relevant for packed bed reactors. Attrition test: Assesses the resistance of catalyst particles to wear and tear under operational conditions, which is critical for fluidized bed reactors. Abrasion test: Determines the catalystâs ability to resist surface wear, which can be crucial in systems involving moving parts or high flow rates. Impact strength test: Evaluates the ability of the catalyst to withstand sudden forces or shocks, which can occur during handling or transportation.
