More Information
Summary: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. The method includes providing an olefin feedstock composition having an alpha-mono-olefin and vinylidene olefins. The method further includes reacting the olefin feedstock composition in the presence of an isomerization catalyst to form an isomerized olefin feedstock comprising the alpha-mono-olefin and branched internal olefins formed from the vinylidene olefins. The method further includes reacting the isomerized olefin feedstock composition and ethylene at metathesis reaction conditions in the presence of a catalyst composition to produce an alphaolefin product comprising the alpha-mono-olefin, linear and branched olefins having fewer carbon atoms than the olefins in the olefin feedstock composition.
