Abstract:
1. A process for oligomerizing isoolefins, the process comprising: feeding an isoolefin to an oligomerization reaction zone; feeding an oxygen-containing reaction moderator, comprising at least one of water, tertiary butyl alcohol or mixtures thereof, to the oligomerization reaction zone; concurrently in the oligomerization reaction zone: recovering an effluent from the oligomerization reaction zone comprising the oligomers and the oxygenated oligomerization byproduct; fractionating at least a portion of the effluent to recover a fraction comprising the oxygenated oligomerization byproduct and the trimers and a fraction comprising the dimers; and blending at least a portion of the fraction comprising oxygenated oligomerization byproduct and trimers with additional hydrocarbons to form a diesel fuel.
