  • Alkylate gasoline composition with renewable naphtha and iso-octane
    Patent number: 10894927
    Abstract: Processes for making alkylate gasoline compositions that are more “green” and alkylate gasoline compositions containing “green” renewable naphtha and iso octane are described. Exemplary processes for making alkylate gasoline compositions that are more “green” and compositions of alkylate gasoline compositions containing “green” renewable naphtha, iso octane and iso pentane are described. Such compositions allow a higher mixing ratio of the renewable naphtha and/or a higher Research Octane Number (RON), Motor Octane Number (MON) and vapour pressure compared to not adding a combination of iso-octane and iso-pentane.
