Abstract:
1. A process for the selective production of synthetic fluid comprising 3.5 to 4.1 cSt viscosity at 100° C., with a Noack volatility weight loss of less than 16%, a Viscosity Index of greater than 120, a Pour Point lower than −50° C., and a viscosity at −40° C. of less than 3000 cSt by: (a) reacting first alpha olefin, excluding 1-decene, in the presence of a first catalyst to form vinylidene olefin; (b) reacting said vinylidene olefin with second alpha olefin, excluding 1-decene, in the presence of BF (c) removing residual unreacted monomers and removing unreacted volatile liquids; (d) hydrogenating bottom product to produce synthetic fluid; (e) wherein said synthetic fluid comprises 3.5 to 4.1 cSt at 100° C.; (f) wherein said synthetic fluid comprises production without heavier than 4.1 cSt at 100° C. co-product; (g) recovering said synthetic fluid.
