  • Patent number: 10767125
    Abstract: Disclosed are Group III base stocks comprising greater than or equal to about 90 wt. % saturated hydrocarbons (saturates); a viscosity index from 120 to 145; a unique ratio of molecules with multi-ring naphthenes to single ring naphthenes (2R+N/1RN); a unique ratio of branched carbons to straight chain carbons (BC/SC); a unique ratio of branched carbons to terminal carbons (BC/TC); and unique MRV behavior as a function of base stock naphthene ratio (2R+N/1RN). A method for preparing the base stocks is also disclosed. Also disclosed is a lubricating oil having the base stock as a major component, and an additive as a minor component.

  • Patent number: 10414701
    Abstract: Systems and methods are provided for forming alkylate from an isoparaffin-containing feed. Olefins for the alkylation reaction can be generated from a portion of the isoparaffin-containing feed. This can be achieved, for example, by using selective oxidation to convert a portion of isoparaffins into alcohol, such as conversion of isobutane to t-butyl alcohol. The alcohol can then be converted to an alkene, such as conversion of t-butyl alcohol to isobutene, in the alkylation reaction environment in the presence of a solid acid catalyst. The solid acid catalyst can then facilitate alkylation of isoparaffin using the in-situ formed alkenes. A catalyst having an MWW framework is an example of a suitable solid acid catalyst.
