    摘要: In a process for isomerizing monoolefins having a terminal double bond (in particular the isomerization of butene-1 to butene-2) in the presence of a Group VIII metal catalyst (in particular an alumina-supported Pd catalyst) which is contaminated by impurities in the monoolefin containing feed, the improvement comprises pretreating the feed with a solid material comprising tin oxide and a refractory support material (in particular alumina).
