Chemical comparisons of liquid fuel produced by thermochemical liquefaction of various biomass materials
Liquefaction of biomass in aqueous alkali at temperatures up to 350/sup 0/C is an effective way to convert solid wastes into liquid fuels. We studied the liquefaction oils of several forms of biomass differing in proportions of cellulose, hemi-cellulose, lignin, protein, and minerals, and compared their chemical composition. We found that the proportions of chemical components varied considerably depending on the type of biomass liquefied. However, all the oils, even those produced from cellulose, had similar chemical characteristics due to the presence of significant quantities of phenols. These phenols are at least partially responsible for the corrosivity and viscosity commonly associated with biomass oils. The differences in chemical component distribution in the various biomass oils might successfully be exploited if the oil is to be used as a chemical feedstock. If the oil is to be used as a fuel, however, then reaction conditions will be a more important consideration than the source of biomass.
