Abstract: Provided herein is a unique process that prepares a saturated hydrocarbon mixture with well-controlled structural characteristics that address the performance requirements driven by the stricter environmental and fuel economy regulations for automotive engine oils. The process allows for the branching characteristics of the hydrocarbon molecules to be controlled so as to consistently provide a composition that has a surprising CCS viscosity at −35° C. (ASTM D5329) and Noack volatility (ASTM D5800) relationship. The process comprises providing a specific olefinic feedstock, oligomerizing in the presence of a BF3 catalyst, and hydroisomerizing in the presence of a noble-metal impregnated, 10-member ring zeolite catalyst.

Abstract: A process for deactivation of an olefin oligomerization catalyst is described, including contacting a catalyst composition with a catalyst quenching medium to form a deactivated catalyst composition, and recovering excess catalyst quenching medium. The catalyst quenching medium includes an alcohol having at least 6 carbon atoms, an organic amine, an amino alcohol, or a combination comprising at least one of the foregoing. The catalyst quenching medium is present in a molar ratio of catalyst quenching medium to catalyst of at least 3:1. A process for the oligomerization of an olefin is also described, including feeding the olefin, a solvent, and a catalyst composition into a reactor, oligomerizing the olefin in the reactor to form a reaction product stream including linear alpha olefins, solvent, and the catalyst composition, and contacting the reaction product stream with a catalyst quenching medium.
