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.
