  • Hydro-Dealkylation Process To Generate High Quality Fuels, Base Stocks And Waxes
    Publication number: 20240368484
    Abstract: Provided are methods of hydro-dealkylation of hydrocarbon feedstock to produce an intermediate hydrocarbon product having a boiling point at T10 of greater than about 500° F.+ by distillation method ASTM D7169 and a viscosity index greater than about 120 in accordance with ASTM D2270 where at least about 50 percent of the hydrocarbon feedstock is a SIMDIS of 400° F. The intermediate hydrocarbon product can be used to produce a base stock, a wax and/or paraffinic diesel.

  • Modified asphalts and methods for producing the same
    Patent number: 11377560
    Abstract: Modified asphalts and methods for producing the same are disclosed. The modified asphalts can include asphalt having a T5 boiling point of 400° C. or more, an olefin compound, and an acid promoter. The modified asphalt can include at least a portion of the olefin compound chemically grafted to at least a portion of the asphalt. The method can include exposing the asphalt, olefin compound, and acid promoter to a temperature of about 160° C. or more.
