Patent ID: 7999143

Claim:
A process for producing a paraffin-rich diesel product from a renewable feedstock comprising: a) adding from about 0.1 to about 30 mass-% water to the feedstock or to a first reaction zone, wherein the mass-% water is measured as mass-% water of the total feed to the first reaction zone including any recycle; b) treating the feedstock and treating the water in the first reaction zone by hydrogenating and deoxygenating the feedstock and converting carbon monoxide and water to carbon dioxide and hydrogen using a catalyst at reaction conditions in the presence of hydrogen to provide a first reaction zone product stream comprising hydrogen, carbon dioxide, and a hydrocarbon fraction comprising n-paraffins having from about 8 to about 24 carbon atoms; c) separating the first reaction zone product stream to form i) a stream comprising hydrogen and carbon dioxide, ii) a stream comprising the hydrocarbon fraction, and iii) a water stream; and d) recovering the hydrocarbon fraction as product.
