Abstract: Commercially beneficial carbon-containing fractions can be recovered from hydrothermal liquefaction reactions in various types of processors. Feedstock slurry from waste solids is placed into a pressurized processor where it is maintained at temperature and pressure for a predetermined period. On discharge from the processor the processed discharge is separated into liquid and solid fractions. Gaseous fractions including carbon dioxide can also be removed or off-taken from the processor. New molecular structures are created in this reaction, resulting in fractions including biogas, biofuels, biosolids and biocrude. Silica, phosphates, potash and low concentration nitrogen based fertilizer, along with carbonaceous material can also be recovered.

Abstract: Described is a novel process for disaggregating biomass pyrolysis oil quantitatively into energy dense hydrophobic aromatic fraction (HAF), fermentable pyrolytic sugars and phenolics based products in a highly economical and energy efficient manner. Phase separation of the esterified pyrolysis oil after an oxidative pre-treatment and the quantitative recovery of the separate fractions is described. Phase separation uses batch as well as continuous reactor systems. The resulting HAF is an energy dense, thermally stable, water free, non-corrosive to carbon steel, and is a free flowing liquid suitable for combustion and for upgrading to transportation fuels. Pyrolytic sugars which are mainly anhydrosugars can be further converted by fermentation to ethanol or other products. Monomeric phenols are useful industrial intermediates and the organic acids in the original pyrolysis oil are mainly recovered as esters of the separation solvents.
