    摘要: Embodiments of methods and apparatuses for processing a renewable feedstock are provided herein. In one example, a method comprises dividing a H2-rich make-up stream into a first H2-rich portion and a second H2-rich portion. The second H2-rich portion has a lower mass flow rate than the first H2-rich portion. The renewable feedstock is deoxygenated in the presence of the first H2-rich portion at hydroprocessing conditions effective to form a deoxygenating reaction zone effluent that contains normal paraffins. At least a portion of the deoxygenating reaction zone effluent is isomerized in the presence of the second H2-rich portion at isomerization conditions effective to form an isomerization reaction zone effluent that contains branched paraffin. The isomerization conditions include a first hydrogen partial pressure of about 4,140 kPa gauge or less.

    摘要: A process to integrate a first biofuels process and a second generation cellulosic biofuels process is provided. The pyrolysis means which produces the char stream and a bioliquid stream. The low pressure hydrotreating component, a high pressure hydrotreating component, the low pressure hydrotreating component which produces the hydrocarbon stream, the high pressure hydrotreating component which produces the steam stream and bioliquid stream. A distillation means, which produces a green gasoline stream and a green diesel stream from the bioliquid stream. The second biofuels process may be a first generation bio-ethanol process, which produces a bio-ethanol stream. The hydrogen production unit, which produces the hydrogen stream and the steam stream. The hydrogen production unit may be a steam reformer or partial oxidation unit.
