ABSTRACT:
The isobutene in C.sub.4 hydrocarbon streams containing from 0.5 to 5% isobutene and n-butenes is reduced preferably to a level of 0.2 mole % or less by passing the feed stream at LHSV 2.5 to 12 in liquid phase through a fixed-bed cation exchange resin catalyst in a tubular reactor with a water heat exchange medium maintained at a temperature of 50.degree. to 80.degree. C., whereby the isobutene is oligomerized and easily separated from the remaining C.sub.4 's by fractionation.
