Several methods are used to measure and evaluate catalyst attrition:
- Attrition Testing: Standardized tests, such as the ASTM D5757 method, involve subjecting catalyst samples to controlled mechanical stress and measuring the amount of fines generated. - Particle Size Analysis: Techniques like laser diffraction or sieve analysis can quantify changes in particle size distribution due to attrition. - Surface Area Measurement: Methods such as BET (Brunauer-Emmett-Teller) analysis assess changes in surface area, which can indicate the extent of attrition.
