Abstract
Processes and systems for stabilization and subsequent hydrogenation of an immiscible olefin are described. In certain embodiments, the hydrogenation is conducted in a fixed bed reactor in presence of a hydrogenation catalyst.
Claims21
A method for hydrogenating an immiscible olefin comprising:
- a) providing a feed stream to the inlet of a fixed bed reactor wherein the feed stream comprises an immiscible olefin and a diluent composition;
- b) contacting the feed stream with hydrogen in the presence of a hydrogenation catalyst at a temperature of about 20° C. or greater thereby producing an effluent;
- c) separating the effluent which comprises a hydrogenated immiscible olefin into a product stream comprising a hydrogenated immiscible olefin and a recycle stream comprising a hydrogenated immiscible olefin;
- d) adding the recycle stream as part of the diluent composition to a stream comprising the immiscible olefin to form a feed stream comprising recycled hydrogenated immiscible olefin;
- and
- e) providing the feed stream comprising recycled hydrogenated immiscible olefin to the inlet of the fixed bed reactor.
