Abstract: Wax compositions may be obtained by providing an olefinic feed comprising a first linear alpha olefin having m carbon atoms and a second linear alpha olefin having n carbon atoms, wherein m and n are independently selected integers each ranging from about 12 to about 100, and the olefinic feed optionally comprises one or more internal olefins and/or one or more branched olefins; contacting the olefinic feed with a metal carbene catalyst in a reactor; forming ethylene and a hydrocarbon substance comprising a linear olefin dimer comprising two carbon atoms less than a sum of m and n; removing the ethylene from the reactor while forming the linear olefin dimer; and isolating a wax composition comprising the linear olefin dimer, a hydrogenated reaction product thereof, or any combination thereof.

Abstract: Wax compositions may be obtained by subjecting one or more linear alpha olefins to olefin metathesis and optionally hydrogenating. The wax compositions comprise: a hydrocarbon substance comprising a linear olefin dimer formed from a first linear alpha olefin having m carbon atoms and a second linear alpha olefin having n carbon atoms, a hydrogenated or partially hydrogenated reaction product of the linear olefin dimer, or any combination thereof, the first linear alpha olefin and the second linear alpha olefin being the same or different, and the linear olefin dimer comprising two carbon atoms less than a sum of m and n; wherein m and n are independently selected integers each ranging from 12 to 100; and wherein the wax composition has a melting point of 25° C. or greater.
