Integrated Process for Production of Diesel Fuel from Renewable Feedstocks and Ethanol Denaturizing

11) An integrated process for producing a branched paraffin-rich diesel product from a renewable feedstock and for denaturing an alcohol comprising;

• a) treating the feedstock in a first reaction zone by hydrogenating and deoxygenating the feedstock using a catalyst at reaction conditions in the presence of hydrogen to provide a first reaction zone product stream comprising hydrogen, water, carbon dioxide, and n-paraffins having from about 8 to about 24 carbon atoms;
• b) separating, in a hot high pressure hydrogen stripper, a gaseous stream comprising hydrogen and at least a portion of the water and carbon dioxide from the first reaction zone product stream and introducing a remainder stream comprising at least the n-paraffins to a second reaction zone to contact an isomerization catalyst at isomerization conditions to isomerize at least a portion of the n-paraffins and generate a branched paraffin-rich stream;
• c) separating a combination of the branched paraffin-rich stream and the gaseous stream to form
• i) a stream comprising hydrogen and carbon dioxide;
• ii) a stream comprising branched paraffins, LPG, and naphtha;
• and
• iii) a water stream
• d) separating the stream comprising branched paraffins, LPG, and naphtha into a diesel product stream and a naphtha and LPG stream;
• e) separating the naphtha and LPG stream into a naphtha stream and an LPG stream;
• and
• f) passing the naphtha stream to an alcohol denaturing process and using at least a portion of the naphtha stream as a denaturant.
