A process that catalytically converts olefinic (Alkenes, typically liquid at standard temperature and pressure) material in thermally cracked streams to meet olefin content specifications for crude oil transport pipelines. A thermally cracked stream or portion of a thermally cracked stream is selectively reacted to reduce the olefin content within a reactor operating at specific, controlled conditions in the presence of a catalyst and the absence of supplemental hydrogen. The process catalyst is comprised of a blend of select catalyzing metals supported on an alumina, silica or shape selective zeolite substrate together with appropriate pore acidic components.

Implementations described herein generally relate to methods for purifying alpha-olefins. The alpha-olefins may be used to form drag reducing agents for improving flow of hydrocarbons through conduits, particularly pipelines. In one implementation, a method of increasing alpha-olefin content is provided. The method includes providing an olefin feedstock composition having an alpha-mono-olefin and at least one of a diolefin having an equal number of carbon atoms to the alpha-mono-olefin and/or a triolefin having an equal number of carbon atoms to the alpha-mono-olefin. The method further includes contacting the olefin feedstock composition with ethylene in the presence of a catalyst composition including an olefin metathesis catalyst. The method further includes reacting the olefin feedstock composition and ethylene at metathesis reaction conditions to produce an alpha-olefin product comprising the alpha-mono-olefin and alpha-olefins having fewer carbon atoms than the alpha-mono-olefin.
