Maximize FCC product yields with a specialty catalyst formulation

A novel catalyst formulation for maximizing propylene yields was studied. The catalyst system is matrix-based and acts as an additive in conventional FCC units. The system can be used in a high-severity FCC unit, in a deep catalytic cracking unit and for the maximization of light olefins. Laboratory studies and field trials to assess the performance of the catalyst were carried out at Hindustan Petroleum Corp Ltd’s Mumbai and Visakh refineries’ FCC units at 10% and 15% inventory changeover. Results showed that the catalyst can be used as an additive in existing FCC units to maximize product yields and selectivity and to increase RON. In a high-olefins FCC unit, the catalyst improves the propylene yield by 1.3 wt%.
