Abstract
A process for dimerizing and oligomerizing olefins to distillate fuels which utilizes a solid acid catalyst for ethylene oligomerization in a first stage and a metal catalyst for further oligomerization in a second stage. Distillate fuels can be produced from the process. Oligomerized olefins may be recycled to the first stage oligomerization reaction to ensure sufficient oligomerization of smaller olefins.
Claims10
A process for oligomerizing an olefin stream comprising:
- oligomerizing said olefin stream with a first stage oligomerization catalyst comprising a solid acid catalyst to produce an oligomerized olefin stream;
- oligomerizing said oligomerized olefin stream with a second stage oligomerization catalyst comprising an amorphous silica-alumina base with a metal to provide an oligomerate stream.
