Direct liquefaction of biomass: results from operation of continuous bench scale unit in liquefaction of water slurries of Douglas fir wood
The Lawrence Berkeley Laboratory's continuous liquefaction unit (CLU) has been successfully operated since July 1981. The operation has been single pass, feeding water slurries of prehydrolyzed Douglas fir wood (LBL process). Significant differences from results with the oil slurry, high oil and water recycle process (PERC process) tested at Albany, Oregon, have been found. The LBL process, at practicable temperatures and residence times, makes somewhat less wood oil and considerably more water-soluble product than does PERC. Consumption of carbon monoxide in LBL, other than by water gas shift reaction, is minimal, as opposed to several tenths of a mole per 100 grams of wood in PERC. Replacement of carbon monoxide with hydrogen as reactant gas makes little or no difference in yield distribution or product analysis. Progress in characterizing the oil and water-soluble product, the overall stoichiometry of the LBL and PERC processes, and the role of formate ion is described.
