  • Selective hydrogenation of crude high-butadiene C4 cuts
    Patent number: 5227553
    Abstract: A process for the selective hydrogenation of butadiene to butenes in the liquid phase or trickle phase in contact with a fixed-bed supported noble metal catalyst, wherein a high-butadiene C.sub.4 stream having a butadiene content of from 20 to 80% w/w, based on the weight of the C.sub.4 stream, is hydrogenated in a cascade of two reaction zones such that the hydrogenation product from the first reaction zone has a butadiene content of from 0.1 to 20% w/w and the hydrogenation product from the second reaction zone has a butadiene content of from 0.005 to 1% w/w, based in both cases on the weight of the C.sub.4 stream, provided that the butadiene content of the hydrogenation product from the second reaction zone is at least 5 times smaller than that of the hydrogenation product from the first reaction zone.
