The compression testing process generally involves the following steps:
1. Sample Preparation: Catalyst pellets or supports are prepared in standard shapes and sizes. 2. Machine Setup: The compression testing machine is calibrated, and the sample is placed between the machine's platens. 3. Loading: A compressive load is gradually applied to the sample until it deforms or breaks. 4. Data Collection: Force and displacement data are collected to generate a stress-strain curve, which helps in analyzing the material's mechanical properties.
