Evolve®

Fluid Catalytic Cracking (FCC) additive for butylenes maximization BASF’s newest additive, Evolve®, maximizes butylenes selectivity and production in the FCCU for refineries who value butylenes production.

Technology
Evolve is BASF’s newest FCC additive that is designed to deliver LPG with preferential selectivity towards butylenes over propylene versus conventional olefin additives. This additive is well suited for refineries that aim to maximize alkylate. Evolve converts gasoline range molecules into valuable LPG products. Refiners that operate at an LPG yield constraint can improve selectivity of FCC olefin products; the butylenes ratio is higher, providing more economic benefit over conventional olefin additives. Evolve leaves conversion unchanged, much like ZSM-5.

Synergize with the best
Evolve works best when combined with a base FCC catalyst that selectively produces high gasoline range olefins for cracking to LPG. This can be realized by matching Evolve with FCC catalyst that maximizes C6 through C9 olefins, providing optimal feed for Evolve to convert to LPG.

Applications
Evolve is a preferred additive for refiners looking to optimize operations via:
•Butylenes selectivity
•Butylenes maximization
•Increased LPG yields
•Increased Alky unit feed
