摘要：
Alkenes, such as normal butenes in a mixed C4 stream are oligomerized, preferably to dimers, which are dimerized in a distillation column reactor over ZSM57 zeolite catalyst at high conversions and high selectivity to octenes. Prior to oligomerization the mixed C4 stream is pretreated to remove dimethyl ether, butadienes and sulfur compounds.
