The abrasion test typically involves subjecting the catalyst particles to a controlled mechanical stress, often using a rotary drum or a vibratory sieve shaker. The catalyst sample is placed in the apparatus, and the machine is operated for a specified duration. The extent of abrasion is then quantified by measuring the weight loss of the catalyst or the amount of fines generated. Standardized procedures and equipment, such as those defined by ASTM or ISO, are often employed to ensure consistency and reproducibility.
