Supercritical extraction and microwave activation of wood wastes for enhanced syngas production and generation of fullerene-like soot particles

This work demonstrated that supercritical carbon dioxide extraction is effective as a pre-treatment technology to generate soot particles with the fullerene-like structure and increase syngas yield from extracted residues during coupled microwave activation gasification. Supercritical removes over half of fatty resin acids needles branches, whereas generates greater yields value-added compounds. The high extractives indicate conversion waste wood for sustainable production chemicals. did not influence solid residue pyrolysis/gasification emphasizing significant potential integrating process into holistic biorefinery. Interestingly, had effect on quality formed. differences in composition led formation needle porous less ordered nanostructure, branches obtained ring graphitic structure. steroids terpenes compared pretreatment indicated type nanostructure.
