Two-step hydrothermal conversion of biomass waste to humic acid using hydrochar as intermediate

Frontiers of Environmental Science & Engineering 2023, Volume 17, Issue 10, doi: 10.1007/s11783-023-1719-8

Abstract: In the first step of the process, hydrochar was prepared at different hydrothermal temperatures and pHTheir chemical properties were then analyzed, and the hydrochar-derived humic acids were produced underThe hydrochar, prepared under high temperature (200 °C) and strong acidic (pH 0) conditions, achievedstage, and 2) increment under the alkaline hydrothermal treatment of hydrochar.The degree of hydrochar unsaturation was suggested as an indicator for evaluating the hydrochar humification

Synthesis of porous carbon from orange peel waste for effective volatile organic compounds adsorption: role of typical components

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 7,   Pages 942-953 doi: 10.1007/s11705-022-2264-x

Abstract: hemicellulose content led to more abundant –COOR, amine-N, and pyrrolic/pyridonic-N in the derived hydrocharUnlike hemicellulose, cellulose reduced the >C=O, amine-N, and pyrrolic/pyridonic-N content of the hydrocharLignin bestowed the hydrochar with slightly increased –COOR, pyrrolic/pyridonic-N, and graphitic-N, and
