The raw C4 cut from steam cracking contains between 35% and 70% butadiene. This cut also contains up to 1.5% vinyl acetylene and 0.7% ethyl acetylene. The modern specification for combined C4 acetylenes in butadiene product is less than 10 ppm. Considerable efficiencies are available by converting vinyl acetylene to butadiene and ethyl acetylene to 1-butene instead of downgrading to fuel.
We have formulated PRICAT™ PD 468 to ensure high C4 acetylene conversion whilst minimising butadiene hydrogenation and green oil formation.
PRICAT PD 468 is available as part of our range of catalysts for olefin processes, please contact us for more information
