  • Patent number: 11247948
    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.

  • Patent number: 11148952
    Abstract: A method of increasing hydrophobicity of a molecular sieve is provided. The method includes: (a) providing a metallosilicate molecular sieve having a framework consisting of oxides of silicon (Si) and a metal (M), wherein M is boron or zinc; (b) contacting the metallosilicate molecular sieve with a liquid aqueous system, thereby obtaining a demetallated molecular sieve having silanol nests and empty framework sites; and (c) thermally treating the demetallated molecular sieve, thereby obtaining a thermally-treated molecular sieve, wherein the thermally-treated molecular sieve (i) retains the three-dimensional framework structure of the metallosilicate molecular sieve and (ii) has a higher Si/M molar ratio as compared to the metallosilicate molecular sieve.

  • Patent number: 11041133
    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.
