Abstract:
1. A process for the oligomerization of alpha-olefins, the process comprising; a) contacting a feedstock of alpha-olefins and at least one oligomerization catalyst in a reactor under oligomerization conditions to oligomerize the alpha-olefins, the feedstock of alpha-olefins being a blend of decene, the decene being present in amounts of 25 to 35 weight % decene, at least 10 weight % octene, and at least 30 weight % dodecene, wherein the weight percentages of the octene, decene, and dodecene in the feedstock yield an average carbon content in the range of 9.9 to 10.5; b) removing unreacted alpha-olefins and dimers of the alpha-olefins to obtain a bottoms intermediate comprising trimers; c) hydrogenating the bottoms product to obtain a hydrogenated product; and d) separating the hydrogenated product to obtain at least two fractions of polyalpha-olefins of differing nominal viscosities.
