Non-Catalytic Dissolution of Biochar Obtained by Hydrothermal Carbonization of Sawdust in Hydrogen Donor Solvent

The production of fuel hydrocarbons from CO2-neutral raw materials is a promising task at present. thermal dissolution biochar obtained by the method hydrothermal carbonization sawdust was studied. in tetralin (hydrogen donor solvent) studied different temperatures (350–450 °C) and with two types dilution mixture tetralin: 1/3 1/4. process proceeded without catalyst. It found that samples subjected to 425–450 °C had highest conversion yield liquid products. reaction temperature also significant effect on composition an increase led benzenes, both direct hexane fraction. A benzene more than 50% observed for fractions 450 °C. suggested possible positive abietates homogenization contributed high process. biochar/tetralin ratio effects products as well. An concentration during hydrocarbon purposes. This undoubtedly due large amount elemental hydrogen involved hydrogenation mixture.
