Fourte®

Innovative Fluid Catalytic Cracking (FCC) Catalyst for butylenes maximization Fourte® maximizes butylenes production in the FCCU and increases gasoline octane while preserving catalyst activity.

Technology
Fourte is BASF’s butylene maximization FCC catalyst developed on the novel Multiple Framework Topologies (MFT) technology. The technology behind Fourte delivers high selectivity toward C4 olefins by optimizing performance across five key factors: rare earth, activity, acid site density, zeolite/matrix ratio and inclusion of a butylene-selective zeolite framework.

Fourte takes advantage of optimized distribution of acid sites, which tempers hydrogen transfer reactions to increase LPG selectivity and butylenes production.

Traditional catalysts suffer from an activity penalty when acid site density is reduced. In contrast, Fourte maintains catalytic activity when maximizing butylenes yield and gasoline octane.
