Abstract
Disclosed is a process and apparatus for switching oligomerization feed between a first oligomerization zone that includes a uni-dimensional small pore zeolite to make more diesel and a second oligomerization zone that includes SPA catalyst for making more gasoline. The diesel can be recycled to make more propylene. The process and apparatus will provide refiners with flexibility to produce the most valuable product commensurate with fluctuating market conditions.
