NOVELTY - Making a fuel composition involves contacting an aromatic-rich biomass derived component and an aromatic-lean component with hydrogen under catalytic hydroprocessing conditions to provide a hydroprocessed biofuel.    USE - For making a fuel composition (claimed) e.g. transportation fuel.    ADVANTAGE - The co-processing results in an upgraded, hydroprocessed product (or an upgraded, hydroprocessed biofuel as a hydroprocessed product fraction) having suitable characteristics, in terms of composition (e.g. quantities of compounds such as aromatic hydrocarbons, present in relatively large or minimally required amounts) and in terms of quality (e.g. quantities of thermally unstable compounds such as oxygenates, present in relatively small amounts) for use as a fuel composition or its component. The method reduces the carbon footprint of the biofuel. The hydroprocessing of both aromatic-rich and aromatic-lean components provides simultaneous upgrading of at least these two components, which, optionally followed by fractionation of the resulting, hydroprocessed product, can provide a hydroprocessed biofuel meeting applicable composition and quality standards. In addition, the oxygenate content of the aromatic-rich component, which is generally significantly higher than that of the aromatic-lean component (e.g. derived from Fischer-Tropsch (F-T) synthesis), is diluted during hydroprocessing. This further simplifies the overall process, by reducing adiabatic temperature rise and the corresponding production of undesirable coke precursors. The biofuel does not require further blending with aromatic hydrocarbons, such as an on-spec aviation biofuel. The generation of hydrogen (i.e. from byproducts obtained from the processing of feedstocks comprising renewable carbon) beneficially reduces the amount of hydrogen that must be obtained from external fossil sources (imported), thus further lowering the lifecycle greenhouse gas (GHG) emission value of the resulting hydroprocessed biofuel. The fuel composition exhibits reduced GHG emissions, based on a lifecycle assessment (LCA) from the time of cultivation of feedstocks (in the case of plant materials) required for the compositions, up to and including the ultimate combustion of the fuel composition by the end user.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a fuel composition comprising a hydroprocessed aviation biofuel obtained from hydroprocessing an aromatic-rich biomass derived component and an aromatic-lean component.
