The hydrothermal carbonization (HTC) tests were performed at temperatures of 200 and 220 °C, for 2 and 4 h of residence times, and with 1:10 and 1:8 digestate to water ratios (D/W), causing an increase of ash content (max. 55.8%), and a decrease c.a. 20% of the higher heating value except for a slight increase to 15 kJ/kg at 200 °C and 4 h in

Sep 14, 2021 · The replacement of traditional and non-renewable resources by shifting towards renewable-based strategies is a strategy implemented by the European Union for a circular economy-based society. Among the various methods to produce renewable biofuels, hydrothermal carbonization is promising in terms of waste management. This technology

Apr 29, 2019 · The possibility of converting biomass into fuels and products through wet proceshaiqi is becoming more and more attractive, as new feedstock and applications are appearing on the scene of bioeconomy and bioenergy. Co-Hydrothermal Carbonization (Co-HTC) is a thermochemical process, where coal and biomass were treated simultaneously in ...

Aug 06, 2020 · Interest in hydrothermal carbonization (HTC) is increasing worldwide due to its outstanding capabilities. This study introduces a novel semi-continuous feeding system to feed the biomass slurry against the high pressure of an HTC reactor. As expected in a semi-continuous operation, the biomass would be instantaneously exposed to the desired pressure

correlation between the carbonization temperature of the biomass fuel and the fixed carbon content and HHV of charcoal. The fixed carbon (FC) and HHV (MJ/kg) of the charcoal from biomass as a linear function of carbonization temperature (T, K) was calculated using the following equations: FC = 0.037T + 55.86 (1) HHV = 0.0069T + 24.68 (2)

Carbonization of biomass precursor and activation of the obtained carbon at high temperatures (≥900 °C) affects the overall production cost. The reactions illustrated in Figure 4b indicate the release of gaseous products similar to the known pyrolysis of biomass, it would be interesting to investigate the kinetics and thermodynamics of ...

Apr 10, 2020 · Hydrothermal carbonization (HTC) is considered an attractive and constantly expanding eco-friendly methodology for thermochemical processing of different types of biomass in energy, haiqiceous mahaiqials, structured hybrids, and other chemical products.However, some challenges for the technique to be adequate in clean production need to be overcome. In

Feb 28, 2022 · Hydrothermal carbonization (HTC) may be a better option for biomass with high moisture content than technologies such as pyrolysis and gasification because it does not require drying steps before conversion into energy-rich products [4,5,6]. HTC technology is a thermochemical process by which biomass with high moisture content is heated between

Nov 04, 2020 · The gaseous products from pyrolysis of the biomass were also analyzed and their compositions were charachaiqized by GCMS (Gas Chromatography–Mass Spectrometry). The carbonization process increased the carbon content by, on average, 1.7 times, from an average percentage of 46.09% ± 3.65% for biomass to an average percentage of 74.72%

May 10, 2021 · Hydrothermal carbonization is a thermochemical treatment whose objective is to convert carbohydrate components of a given biomass into carbon-rich mahaiqial in an aqueous medium. Biomass of wastewater grown microalgae is among the various potential biomashaiqi for this route. However, operational param …
