Abstract:
1. A process for producing a hydrocarbon product comprising paraffins having from about 8 to about 24 carbon atoms from a renewable feedstock comprising; treating the renewable feedstock in a reaction zone in the presence of hydrogen by hydrogenating and deoxygenating the renewable feedstock at reaction conditions to provide a reaction product comprising n-paraffins having from about 8 to about 24 carbon atoms, and recycling a portion of the reaction product to the reaction zone wherein the reaction zone is operated at a pressure in the range of about 1379 kPa absolute (200 psia) to about 4826 kPa absolute (700 psia); wherein the renewable feedstock further comprises at least one co-feed component selected from the group consisting of spent motor oils, spent industrial lubricants, used paraffin waxes, liquids derived from the gasification of coal followed by a downstream liquefaction step, liquids derived from the gasification of biomass followed by a downstream liquefaction step, liquids derived from the gasification of natural gas followed by a downstream liquefaction step, liquids derived from depolymerization, thermal or chemical, of waste plastics, and synthetic oils generated as byproducts from petrochemical and chemical processes.
