Abstract
A process for the separation of conjugated olefins from monoolefins in a fluid comprising such conjugated olefins and monoolefins using a Diels-Alder reaction to provide a fluid comprising a Diels-Alder adduct and monoolefins. The fluid comprising such Diels-Alder adduct and monoolefins can be subjected to a separating means to thereby recover a resulting monoolefin-containing fluid containing less than about 50 parts per million conjugated olefins. The process is particularly useful for purification of fluids containing normal alpha olefins.
Claims20
A process for purifying a monoolefin stream, comprising:
- contacting a gaseous monoolefin stream comprising one or more monoolefins with a Diels-Alder dienophile to convert one or more conjugated olefins present in the monoolefin stream to a Diels-Alder adduct;
- and removing the Diels-Alder adduct from the monoolefin stream, thereby purifying the monoolefin stream such that it comprises less than about 50 parts per million (ppm) conjugated olefins.
