Abstract
A process for preparing an olefin stream for oligomerization comprises fractionating an olefin stream to provide a light gas stream and a olefin rich stream. The olefin rich stream is selectively hydrogenated to convert diolefins to mono-olefins and provide a mono-olefin stream and oligomerizing the mono-olefin stream over an oligomerization catalyst to provide an oligomerized stream.

A process for processing an olefin stream comprising:
- converting methanol to provide an olefin stream;
- fractionating said olefin stream to provide a gas stream and an olefin rich stream;
- selectively hydrogenating said olefin rich stream to convert diolefins to mono-olefins and provide a mono-olefin stream;
- and
- oligomerizing said mono-olefin stream over an oligomerization catalyst to provide an oligomerized stream.
A process for processing an olefin stream comprising:
- converting methanol to provide an olefin stream;
- fractionating said olefin stream to provide a gas stream and an olefin rich stream;
- absorbing oxygenates from said olefin rich stream into a water wash stream to provide an oxygenate rich water wash stream and a washed olefin rich stream;
- selectively hydrogenating said washed olefin rich stream to convert diolefins to mono-olefins and provide a mono-olefin stream;
- and
- oligomerizing said mono-olefin stream over an oligomerization catalyst to provide an oligomerized stream.
A process for processing an olefin stream comprising:
- sending a vaporous olefin stream and a liquid olefin stream to a fractionation column;
- fractionating said vaporous olefin stream and said liquid olefin stream to provide a gas stream and an olefin rich stream;
- selectively hydrogenating said olefin rich stream to convert diolefins to mono-olefins and provide a mono-olefin stream;
- and
- oligomerizing said mono-olefin stream over an oligomerization catalyst to provide an oligomerized stream.
