Abstract

See full text

Embodiments disclosed herein relate to a process for the oligomerization of olefins, the process including at least one olefin feedstream that includes ammonia and contacting the at least one olefin feedstream with a liquid including alkaline water to remove at least a portion of the ammonia to produce at least one treated olefin feedstream and subsequently contacting the at least one treated olefin feedstream with a catalyst under oligomerization conditions to produce an oligomer product. In several embodiments disclosed herein, the at least one olefin feedstream includes one or more C3-C15 olefins, preferably, C3-C5 olefins, any isomer thereof, one or more paraffins having the same or different carbon number as the olefins, and mixtures thereof.
