ISOBUTENE REMOVAL FROM C.SUB.4 STREAMS

摘要

ISOBUTENE REMOVAL FROM C4 STREAMS The isobutene in C4 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 to 80.degree.C, whereby the isobutene is oligomerized and easily separated from the remaining C4 by fractionation.
