Upgrading biomass liquefaction products through hydrodeoxygenation
Products of direct liquefaction of wood at high pressure have been converted by catalytic hydrogenation to a gasoline-like hydrocarbon product. The process operates at a temperature of 300-350 degrees C and a pressure of 2000 psig with nickel metal or sulfided cobalt-molybdenum catalyst. The catalysts are commercially available hydrotreating catalysts. Other tests have shown a copper-chromite catalyst and the unsulfided form of the cobalt-molybdenum catalyst to be less effective. Analysis of infrared spectrophotometry, gas chromatograph/mass spectrometry, and nuclear magnetic resonance in addition to determination of elemental compostion, density, and distillation range were used to evaluate the product compostion.
