Hydrothermal Carbonization: A Review
Chemie Ingenieur Technik, 2011AbstractDie hydrothermale Carbonisierung (HTC) eröffnet eine verfahrenstechnisch praktikable Möglichkeit, um aus einer Vielzahl von organischen Rest‐ und Abfallstoffen wertvollere Produkte zu erzeugen. Diese können Humus oder eine Art Biokohle sein, die als lagerfähiger und leicht zu transportierender Brennstoff oder evtl.

Facile Polymer Functionalization of Hydrothermal‐Carbonization‐Derived Carbons
Macromolecular Rapid Communications, 2013AbstractA simple and efficient polymer grafting onto hydrothermal carbonization (HTC)‐derived materials is described. The method pertains to the Diels–Alder cycloaddition reaction of furan moieties present on the surface of a HTC material with the maleimide groups stemming from a maleimide protected poly(ethylene glycol) (Me‐PEG‐MI) by a retro Diels ...

Hydrothermal carbonization of olive mill wastewater
Bioresource Technology, 2013Hydrothermal carbonization (HTC) is an emerging technology to treat wet biomasses aimed at producing a biochar material. Herein, olive mill wastewater (OMW) was subjected to HTC. Mass balance considerations provide evidence that the yield of biochar is low (~30%, w/w), which is associated with a low fraction of carbohydrates in OMW.

Hydrothermal carbonization of poly(vinyl chloride)
Chemosphere, 2015Poly(vinyl chloride) (PVC) was subjected to hydrothermal carbonization in subcritical water at 180-260 °C. Dehydrochlorination increased with increasing reaction temperature. The release of chlorine was almost quantitative above ∼235 °C. The fraction of organic carbon (OC) recovered in the hydrochar decreased with increasing operating temperature from ...

Hydrothermal carbonization of Chinese fan palm
Bioresource Technology, 2019This study provided a detailed observation on hydrothermal carbonization (HTC) of Chinese fan palm. The heating value and chemical exergy was calculated. As the reaction severity increased, both heating value (18.84-27.61 MJ/kg) and chemical exergy (21.07-29.06 MJ/kg) had increase trend.

Hydrothermal carbonization of pulp mill streams
Bioresource Technology, 2016The progress of the conversion, the yield, the structure and the morphology of the produced carbonaceous materials as a function of time were systematically studied with pyrolysis-GC/FID and FESEM microscope. The conversion of galactoglucomannan, bleached kraft pulp and TEMPO oxidized cellulose nanofibrils followed the reaction route of glucose being ...

Hydrothermal carbonization of coffee silverskins
Biocatalysis and Agricultural Biotechnology, 2021Abstract If waste biomass from food processing can be harnessed to create new bioproducts, it will not pollute the environment by its disposal. Hydrothermal carbonization (HTC) has been found to be effective on some types of biomass to produce a solid fuel product and a sugar-rich liquid product.

Properties and Degradability of Hydrothermal Carbonization Products
Journal of Environmental Quality, 2013Biomass carbonized via hydrothermal carbonization (HTC) yields a liquid and a carbon (C)-rich solid called hydrochar. In soil, hydrochars may act as fertilizers and promote C sequestration. We assumed that the chemical composition of the raw material (woodchips, straw, grass cuttings, or digestate) determines the properties of the liquid and solid HTC ...

Hydrothermal Carbonization of Municipal Waste Streams
Environmental Science & Technology, 2011Hydrothermal carbonization (HTC) is a novel thermal conversion process that can be used to convert municipal waste streams into sterilized, value-added hydrochar. HTC has been mostly applied and studied on a limited number of feedstocks, ranging from pure substances to slightly more complex biomass such as wood, with an emphasis on nanostructure ...

Elements, 2014
Graphitic carbon deposited from hydrothermal fluids occurs globally, in rocks from all depths in Earth's crust and ranging in age from Precambrian to Tertiary. The varieties of deposits include graphitic cones and “artichokes” filling rock pores, explosively injected veins, graphitic pegmatites with platinum-bearing ores, and isochemical–“iso-isotopic”
