NOVELTY - Producing hydrocarbon product from renewable feedstock (100) with at least tall oil, comprises: (a) heating the feedstock at 60-80 degrees C; (b) conducting the feedstock to a reaction zone at same temperature; (c) treating the feedstock in the zone by hydrogenation and deoxygenation to provide a reaction product (106) containing 8-24C paraffins, and recycling a portion of the product to the reaction zone; and (d) isomerizing at least a portion of paraffins in an isomerization zone (116) by contacting with an isomerization catalyst to form branched-paraffins (122) and the hydrocarbon product.    USE - The process is useful for producing a hydrocarbon product, which is a diesel boiling range hydrocarbon product (claimed) that is useful as a fuel.    ADVANTAGE - The process: utilizes renewable feedstock and co-feed component; increases the hydrogen solubility in the reaction mixture and recycles a portion of hydrocarbon in treatment zone, thus allowing successful operation at lower pressures and reducing cost; operates with high recycle and maintaining high levels of hydrogen in the liquid phase to dissipate hot spots at the catalyst surface, thus reducing the formation of undesirable heavy components which lead to coking and catalyst deactivation; and provides high hydrocarbon recycle operations to dilute any heavy components in the feedstock and avoids formation of gums which plug pre-heaters and the reactor.    DETAILED DESCRIPTION - Producing a hydrocarbon product from a renewable feedstock (100) comprising at least tall oil, comprises: (a) heating the feedstock at 60-80 degrees C; (b) conducting the feedstock to a reaction zone while maintaining the same temperature; (c) treating the feedstock in the reaction zone by hydrogenating and deoxygenating the feedstock at reaction conditions to provide a reaction product (106) containing 8-24C paraffins, and recycling a portion of the reaction product to the reaction zone, where the volume ratio of recycle to feedstock is 2:1-8:1; and (d) isomerizing at least a portion of the paraffins in the reaction product in an isomerization zone (116) by contacting with an isomerization catalyst at conditions to isomerize at least a portion of the paraffins to branched-paraffins (122) and generate the hydrocarbon product. An INDEPENDENT CLAIM is also included for a blended fuel produced by the above process.
