ABSTRACT:
The isobutene in C.sub.4 hydrocarbon streams containing 5 to 60 mole % isobutene and n-butenes may be reduced to a level of 0.2 mole % or less by passing the feed stream at LHSV 0.5 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 30.degree. to 80.degree. C., whereby the isobutene is oligomerized and easily separated from the remaining C.sub.4 by fractionation.
