Sewage sludge treatment via hydrothermal carbonization combined with supercritical water gasification: Fuel production and pollution degradation

Sustainable hydrothermal carbon for advanced electrochemical energy storage

“…33,34,103 Diverse types of biomass have been subjected to the HTC process, ranging from model substances to intact biomass including cellulose, 104,105 glucose, 104,106 agricultural residue, 107 animal manure, 108 municipal solid waste, 109,110 and sewage sludge. 111 Briefly, HTC technology is presumably close to natural coalification 112 and it is often conducted under moderate conditions in the temperature range of 180–280 °C in a confined system. 113,114 The reaction pressure is autogenic with the saturation of water vapor pressure corresponding to the reaction temperature.…”

Production of green hydrogen from sewage sludge / algae in agriculture diesel engine: Performance Evaluation

“…Moreover, recent research promotes the catalysts for hydrogen production due to their excellent performance compared to conventional methods [ 20 ]. In addition, the sewage sludge treated by hydrothermal gasification process promised hydrogen was utilized as an alternative fuel for minimized pollution degradation [ 21 ]. Bora et al [ 22 ] reviewed and summarized the sustainable approach for gathering alternative fuel from sewage wastewater.…”
