PROCESS FOR PREPARING A C4-OLEFIN MIXTURE BY SELECTIVE HYDROGENATION AND METATHESIS PROCESS FOR USING THIS STREAM

摘要

A C4-olefin mixture having a 1,3-butadiene content of from 100 to 500 ppm and a content of 1,2-dienes of less than 10 ppm is described. The present invention further provides a process for preparing this C4-olefin mixture and provides for its use in a metathesis reaction for preparing 2-pentene and/or 3-hexene.
