Abstract
An improved process for oligomerizing olefins is provided in which olefin feed is contacted with phosphoric acid catalyst to form an olefin oligomerization product containing phosphorous-containing foulant precursors. The olefin oligomerization product is then contacted with a foulant adsorbent comprising at least one member selected from the group consisting of alumina, activated alumina and magnesium oxide in an amount and under conditions sufficient to effect removal of at least a portion of said foulant precursors. The treated olefin oligomerization product stream can then be passed to downstream recovery and process equipment with minimized fouling.
