A ethene-rich feedstock is oligomerised over a shape selective zeolitic catalyst. After cooling the effluent is separated in a light gas stream, which is recycled and a liquid intermediate stream, which is sent to a second oligomerization zone. The effluent of this zone is cooled and separated into a distillate-rich product and a vapor stream which is recycled and combined with the effluent of the first reaction zone, before its separation. |
