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: Provided herein are hydrocarbon mixtures with controlled structure characteristics that address the performance requirements for finished lubricants driven by the stricter environmental and fuel economy regulations. The branching characteristics of the hydrocarbon molecules are controlled to provide a composition that has a unique and superior viscosity-temperature relationship and Noack volatility. An important aspect of the present invention relates to a saturated hydrocarbon mixture with at least 80% of the molecules having an even carbon number, with the branching characteristic of BP/BI in the range≥−0.6037 (Internal alkyl branching)+2.0, where on average at least 0.3 to 1.5 of the internal methyl branches are located more than 4 carbons away from the terminal carbon when analyzed by carbon NMR. The saturated hydrocarbon mixture with such unique branching structure consistently exhibits a stand out performance in the cold crank simulated viscosity (CCS) vs Noack volatility relationship, which allows for the formulation of lower viscosity engine oils with improved fuel economies.

Abstract: A hydrocracking catalyst comprising a zeolite beta having an average domain size from 800 to 1500 nm2; a zeolite USY; a catalyst support; and at least one metal selected from the group consisting of elements from Group 6 and Groups 8 through 10 of the Periodic Table. The zeolite beta has an OD acidity of 20 to 50 μmol/g and the catalyst support comprises an amorphous silica aluminate and a second support material when the weight percentage content of the zeolite beta is less than the weight percentage of the zeolite USY, and, when the weight percentage content of the zeolite beta is greater than the weight percentage of the zeolite USY, the zeolite beta has an OD acidity of 20 to 400 μmol/g, the zeolite beta content is from 0.5 to 10 wt. % and the zeolite USY has an ASDI between 0.05 and 0.12 with a corresponding zeolite USY content of from 0 to 5 wt. %. A process for hydrocracking a hydrocarbonaceous feedstock using the catalyst is also described as is a method for making the hydrocracking catalyst.
