Catalytic gasification of dewatered sewage sludge in supercritical water: Influences of formic acid on hydrogen production

Catalytic Gasification of Sewage Sludge in Supercritical Water: Influence of K2CO3 and H2O2 on Hydrogen Production and Phosphorus Yield

“…Meanwhile, the CO and CH 4 yields hardly changed with an increase in the K 2 CO 3 concentration. These results agreed with previous reports, which showed slight changes in the CO and CH 4 yields with increasing K 2 CO 3 . , , The comparison of this study with previous literature − is shown in Table .…”

Catalytic liquefaction of municipal sewage sludge over transition metal catalysts in ethanol-water co-solvent

“…The utilization of MSS has aroused interests recently, and various methods were applied by researchers ( Caporgno et al, 2016 , Choi et al, 2017 , He et al, 2014 , Papa et al, 2017 , Thomsen et al, 2017 ). As a fast-developing thermochemical conversion method, direct liquefaction is a promising technology to handle the treatment of MSS and produce liquid fuel biocrude simultaneously ( Fan et al, 2016 , Lemoine et al, 2013 ).…”

Water-catalyzed conversion of glucose to small molecules during hydrothermal carbonization: a density functional theory study

“…2,3 Consequently, much attention has been drawn to the development of sludge treatment methods, among which the wet conversion of sludge into biochar via hydrothermal carbonization (HTC) holds great promise. 4 HTC is a thermochemical process using water as a liquid reaction medium under subcritical conditions to reduce the H and O contents of biomass through dehydration and decarboxylation and transform the raw materials into carbon-containing products. 5 Generally, HTC affords hydrochar, a large quantity of liquid products, and a small quantity of gaseous products.…”
