Fluid catalytic cracking (FCC) processes employ microspheroidal catalyst particles, which play a significant role in the most important part of a refinery. These catalysts are subject to attrition because of the nature of FCC process circulation in the reactor regenerator. Attrition tests according to the American Society for Testing and Materials (ASTM) standards were carried out for two FCC catalysts in both fresh and spent forms. Attrition characteristics and catalyst resistance were investigated by particle size distribution and scanning electron microscopy. Response surface methodology using a central composite design was applied to simulate the mass distribution of samples in the downstream. This method was used to investigate the effect of time on attrition behavior of fresh and spent forms of the catalysts.
