ABSTRACT:
The invention concerns selectively hydrogenating butadiene to butene in a C.sub.4 fraction containing at least 30 weight % butene-1 by treatment with hydrogen under carefully controlled conditions which comprise in combination use of a supported palladium catalyst containing about 0.01 to about 1.0 weight % palladium, a small excess of hydrogen over theoretical, temperatures in the range of about 50.degree. to 90.degree. C., pressures sufficient to maintain the hydrocarbons in a mixed vapor-liquid phase and a mass velocity of above 1500 lbs./(Sq. ft..times.H).
