1. A process comprising:
providing an olefinic feed in a reactor, the olefinic feed comprising a first linear alpha olefin having m carbon atoms and a second linear alpha olefin having n carbon atoms, the first linear alpha olefin and the second linear alpha olefin being the same or different, wherein m and n are independently selected integers each ranging from 12 to 30, and the olefinic feed comprises 85 weight percent (wt %) to 100 wt % of linear alpha olefins, 0 wt % to 15 wt % of internal olefins, 0 wt % to 15 wt % of branched olefins, or a combination thereof, based on the olefinic feed;
contacting the olefinic feed with a metal carbene catalyst in the reactor in a continuous production mode, at a temperature of 60° C. to 75° C. and the metal carbene catalyst is contacted with the olefinic feed at a concentration of 10 ppm or less of the metal carbine catalyst;
forming ethylene and a hydrocarbon substance comprising a linear olefin dimer in the reactor in the continuous production mode, the linear olefin dimer being formed from the first linear alpha olefin and the second linear alpha olefin, the 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;
contacting the linear olefin dimer with a hydrogenation catalyst under hydrogenation reaction conditions, and hydrogenating at least a portion of the linear olefin dimer to form a linear paraffin product, optionally in a presence of the metal carbene catalyst; and
isolating a wax composition comprising the linear olefin dimer, a hydrogenated reaction product thereof, or any combination thereof.
