6 Claims

1. In a process for the oligomerization of olefins comprising contacting a feed containing olefin monomers with at least one oligomerization catalyst having the TON and/or MFS structure under oligomerization conditions, including a reaction temperature, to produce a product selected from the group consisting of dimers, trimers, and mixtures thereof, of said olefin monomers, the improvement comprising said feed being further characterized by having from 1 to 100 ppm by volume sulfur-containing compounds and increasing the reaction temperature with time the catalyst is on stream.
