Menetelmä olefiinin tai olefiinien seoksen muuttamiseksi

摘要

The invention relates to a process for the conversion of an olefin or a mixture of olefins in a distillation column in which both a metathesis and an isomerization reaction occur. The invention is characterized in that in the top section a metathesis reaction takes place and that in the bottom section a combined metathesis and isomerization reaction takes place. Regeneration of deactivated catalyst is carried out by treatment with an olefin, followed by treatment with an oxygen-containing gas and subsequently with a nitrogen-containing gas.
