Fluid catalytic cracking (FCC) is one of the most important conversion processes used in refineries. This process converts heavy petroleum fractions into lighter, higher-value products, such as gasoline, propylene and others. FCC units (FCCUs) have the flexibility to process a wide range of feedstocks, and at varying severities, to optimize refinery profitability. Maximization of propylene production from FCCUs has become a means for refiners to maintain their competitiveness. This article provides insight into an advanced propylene maximization catalytic cracking (PMCC) technologya that integrates process, hardware and catalyst. The technology’s propylene yield is higher than any other FCC
