  • FLUID CATALYTIC CRACKING ADDITIVE COMPOSITION FOR ENHANCED BUTYLENES SELECTIVITY OVER PROPYLENE
    Publication number: 20240001351
    Abstract: Disclosed herein in certain embodiments is a fluid catalyst cracking (FCC) additive composition that includes a first component, a second component, and optionally a third component. The first component includes beta zeolite and a first matrix. The second component includes ZSM-5 zeolite and a second matrix. The third component includes Y zeolite and a third matrix. The components are present in the additive composition in a range that provides for enhanced butylenes to propylene selectivity ratio and total butylenes yield when catalytically cracking a hydrocarbon feed.
