Hydrothermal carbonization (HTC) has emerged as a pivotal technology in the battle against climate change and fosters circular economies. Operating within unique reaction environment characterized by water solvent moderate temperatures at self-generated pressures, HTC efficiently converts biomass residues into valuable bio-based products. Despite HTC’s potential—from management of challenging wastes to synthesis advanced carbons implementation biorefineries—it encounters hurdles...
Hydrothermal carbonization (HTC) solid and liquid products may inhibit seed germination, necessitating post-treatment. The hydrothermal humification (HTH) method addresses this drawback by transforming inhibitory compounds, such as aromatics, into artificial humic acids (AHAs) fulvic (AFAs). This study introduces a novel approach investigating the substitution of commonly used alkaline agent in HTH, KOH, with hydrated lime to develop cost-effective fertilizers from sugar beet pulp, enriching...
This study presents a new strategy for the production of sustainable manganese fertilizer based on artificial humic substances (AHS). AHS with different concentrations (0‒20%) were synthesized from poplar bark under alkaline conditions via hydrothermal treatment. For 20% formulation, interaction resulted in reduced solubility (from 25.2% to 12.3% organic carbon) and average molecular weight acids 11.6 3.9 KDa), indicating preferential binding high-molecular-weight fraction. The formulation...
Abstract Hydrothermal carbonization (HTC) converts wet biomass into hydrochar and a process liquid, but aromatic compounds in the products have been reported as roadblock for soil applications they can inhibit germination, plant growth, microbial activity. Here, we compared HTC hydrothermal humification (HTH) of cow manure digestate while varying initial alkaline content by adding KOH. HTH converted 37.5 wt% feedstock to artificial humic acids (A-HAs) found both solid twice that HTC. reduced...
Although many studies have investigated the hydrothermal transformation of feedstock biomass, little is known about stability compounds present in process liquid after carbonization completed. The physicochemical characteristics (HTC) products may change over storage time, diminishing amount desired or producing unwanted contaminants. These changes restrict use HTC products. Here, we investigate effect temperature (20, 4, and -18 °C) time (weeks 1-12) on structural compositional selected...
Abstract Limited information is available about potential physicochemical changes that can occur in hydrochar post-production, e.g. during drying and storage. Understanding these crucial not just for shaping future research plans, but also practical applications. Here we studied the effect of moisture (69.2% 2.4%) three storage temperatures (− 18, 4, 20 °C) over a year on selected organic inorganic compounds produced from Hydrothermal carbonization (HTC) digested cow manure. Comparison...
Integrated biorefineries play a transformative role in sustainable development by converting biomass and biogenic residues into high-value products while minimizing waste, emissions, resource inefficiencies. This review explores innovations biorefinery processes, emphasizing the synergy between thermochemical, biochemical, biological technologies such as pyrolysis, fermentation, anaerobic digestion, hydrothermal carbonization, algae insect systems. Recent advancements, including humification...
The hydrothermal carbonization (HTC) process has been found to consistently improve biomass fuel characteristics by raising the higher heating value (HHV) of hydrochar as severity is increased. However, this usually associated with a decrease in solid yield (SY) hydrochar, making it difficult determine optimal operating conditions obtain highest energy (EY), which combines two parameters. In study, graph-based genetic programming (GP) method was used for developing correlations predict HHV,...
The solubility of fulvic acid was tuned through acid-catalyzed condensation with phloroglucinol and glyoxylic to enable prolonged delivery its beneficial properties, such as complexation, buffering, transport vitamins minerals, soil.
This study investigated the efficiency of hydrochar derived from hydrothermal fulvification wheat straw in adsorbing malachite green (MG) dye. The characterizations samples were determined using various analytical techniques like SEM, EDX, FTIR, X-ray spectroscopy, BET surface area analysis, ICP-OES for determination inorganic elements, elemental analysis through ultimate and HPLC content sugars, organic acids, aromatics. Adsorption experiments demonstrated that exhibited superior removal...
