601362 Disclosed herein is a process for producing a hydrocarbon product from a renewable feedstock comprising at least tall oil, said process comprising; heating the renewable feedstock comprising at least tall oil to a temperature of from 60 degree C to 80 degree C; conducting the renewable feedstock to a reaction zone while maintaining the temperature of the renewable feedstock at from 60 degree C to 80 degree C; treating the renewable feedstock in the reaction zone by hydrogenating and deoxygenating the feedstock at reaction conditions to provide a reaction product comprising paraffins having from 8 to 24 carbon atoms, and recycling a portion of the reaction product to the reaction zone wherein the volume ratio of recycle to feedstock is in the range of 2: 1 to 8: I; and isomerizing at least a portion of the paraffins in the reaction product in an isomerization zone by contacting with an isomerization catalyst at isomerization conditions to isomerize at least a portion of the paraffins to branched-paraffins and generate the hydrocarbon product. Additionally disclosed is wherein the process further comprises pre-treating the renewable feedstock in a pre-treatment zone at pre-treatment conditions to remove alkali metals. Additionally disclosed is wherein the process further comprises treating a petroleum hydrocarbon feedstock in the reaction zone. Additionally disclosed is wherein the process further comprises blending a portion of the branched paraffins with petroleum derived hydrocarbon to generate a blended fuel. |
