THERMOCHEMICAL CONVERSION Thermal conversion processes use heat as the dominant mechanism to convert biomass into another chemical form. Bio-oil can be used as a heating fuel or can be further converted to advanced biofuels. and scale-up from bench to pilot scale. Current areas of research and analysis at NREL focus on catalyst Conversion quality and contents or makeup of the synthesis gas One such char product, known asbiochar, may be used as a soil or compost additive to sequester carbon in the soil. gas, synthetic natural gas, or other mixed oxygenates) for the production of fuels, Wood Sci Technol 1:4570.

In pyrolysis processing, biomass feedstocks are broken down using heat in the absence of oxygen, producing a biooil that can be further refined to a hydrocarbon product. Oil The production of fuels by cellulose liquefaction. Biomass gasification is a thermochemical process of converting solid biomass into a gaseous fuel known as synthesis gas or producer gas under a reduced oxygen atmosphere to avoid complete combustion [ 59, 60 ].
