Systems and methods of converting renewable feedstocks into intermediate hydrocarbon blend stocks and transportation fuels

A process to provide renewable transportation fuels, the process comprising:

• converting sugar in one or more reactors into an intermediate renewable hydrocarbon blend stock within the one or more reactors;
• passing the intermediate renewable hydrocarbon blend stock through a first separation unit, thereby to separate out at least a first sustainable aviation fuel blend stock that contains one or more of synthesized kerosene (SK) or synthesized aromatic kerosene (SAK);
• operating a renewable diesel unit, thereby to yield a renewable diesel product from one or more lipids in the renewable diesel unit;
• passing the renewable diesel product through a second separation unit to separate out at least a second sustainable aviation fuel blend stock that has at least one of hydroprocessed esters and fatty acids-synthetic paraffinic kerosene (HEFA-SPK);
• blending at least the first sustainable aviation fuel blend stock and the second sustainable aviation fuel blend stock so that a resulting blend defines a sustainable aviation fuel.

A process to provide renewable transportation fuels, the process comprising:

• converting sugar into an intermediate renewable hydrocarbon blend stock;
• passing the intermediate renewable hydrocarbon blend stock through a first separation unit to separate out at least a sustainable marine fuel blend stock;
• operating a renewable diesel unit having one or more lipids therein, thereby to yield a renewable diesel product from the one or more lipids;
• passing the renewable diesel product through a second separation unit to separate out at least a renewable diesel;
• and
• blending at least the sustainable marine fuel blend stock and the renewable diesel so that the resulting blend defines a sustainable marine fuel.

A system to provide renewable transportation fuels, the system comprising:

• one or more reactors, having an inlet to receive sugar and an outlet, configured to hydrogenate the sugar, hydrodeoxygenate the hydrogenated sugar, and facilitate acid condensation of the hydrodeoxygenated, hydrogenated sugar when the sugar is positioned in the one or more reactors, thereby to produce an intermediate renewable hydrocarbon blend stock;
• a first separation unit connected to and in fluid communication with the outlet of the one or more reactors, the first separation unit operable to separate the intermediate renewable hydrocarbon blend stock into at least an intermediate renewable gasoline blend stock;
• a renewable diesel unit having an inlet to receive one or more lipids and an outlet, the renewable diesel unit configured to yield a renewable diesel product from the one or more lipids when positioned in the renewable diesel unit;
• a second separation unit connected to and in fluid communication with the outlet of the renewable diesel unit, the second separation unit operable to separate the renewable diesel product into at least a renewable diesel blend stock and a low-grade naphtha, the low-grade naphtha having a benzene content less than about 0.5 volume percent and a research octane number of less than about 60;
• and
• a blending unit to blend together at least the intermediate renewable gasoline blend stock from the first separation unit and the low-grade naphtha from the second separation unit.
