Hydrodeoxygenation of wood-derived liquids to produce hydrocarbon fluids
Catalytic hydrotreating of wood-derived liquids is being studied at Pacific Northwest Laboratory. Using a continuous-feed, fixed-bed reactor, commercial hydrotreating catalysts and conditions are used to hydrodeoxygenate and hydrocrack the products of biomass liquefaction. Experiments are performed in an upflow reactor wherein both liquid phase and gas phase reactions are considered to be important. Although hydrocarbons are not produced in any significant amount by thermochemical direct liquefaction of wood, the use of secondary hydrogenation step to treat the initial product can result in nearly pure hydrocarbons. These hydrocarbons are primarily cyclics and aromatics which would be useful in gasoline blending. Experimental results with either cobalt/molybdenum or nickel/molybdenum catalyst show that deoxygenation of the primarily phenolic wood oil is achieved in either case. The extent of saturation of the liquid product is dependent on catalyst type, operating temperature and relative flows of oil feedstock and hydrogen gas. 23 references, 1 figure, 5 tables.
