A population balance model has been developed for catalyst propemes, which IS m good agreement with commercml flmd crackmg data The apphcatlon of Markov theorv gives a detaded account of the volume, age, actlvlty, and residence time of catalvsts for each oartlcle size class This model has been used

The rate of attrition of a catalyst rample, of a single particle size, can be expressed by a simple function of initial diameter and time. The initial rate is a function of initial diameter, whereas the decrease in attrition rate of a catalyst of a given size as it ages depends only on time. The at
