Polycarbon biofuels may be made from feedstock such as wood waste, agricultural wastes and waste paper. The feedstock may be cooked under acidic conditions to convert cellulose and similar material in the feedstock into a biofuel that is hydrophobic, readily pelletized, and has a high energy density. The biofuel may be blended with coal or other fuels to provide blended fuels that may be burned in conventional burners. One process forms a slurry of the feedstock, sparges carbon dioxide through the slurry to achieve a pH below 5 and cooks the slurry at temperatures in the range of 170 C to 300 C until conversion of the feedstock to polycarbon biofuel has occurred. The biofuel may be separated from liquids in the slurry by filtration. |
