“…In contrast, a much narrower range of cadmium sorption capacities was found for plant-based and manure-based HCs and pyrochars (13.9-81.32 mg/g). The values for Cd (II) sorption on manure-derived pyrochars (33.44-81.32 mg/g) ( [73]) were significantly higher than those for HCs (13.9-38.3 mg/g) [69,71,73,87], even with KOH-activation (30.40-40.78 mg/g; [65,67], and plant-derived pyrochars (29.9 mg/g) [87]. A similar behavior for antimony sorption was seen [69].…”

“…Álvarez-Murillo et al [24] and Moon et al [64] found similar results using olive stone and sewage sludge, respectively. On the other hand, Lin et al [65] found that HTC as a pretreatment improved the CO 2 gasification of municipal solid wastes (MSW), promoting a higher reactivity. Furthermore, Gunarathne et al [66] accomplished a study in a continuous updraft gasifier located in a pilot plant, gasifying HC from spent grains from a brewery.…”

“…The char surface properties are mainly influenced by the feedstock and production method (e.g., pyrolysis, hydrothermal carbonization, vapor-thermal carbonization) [65,84]. Post-processing steps (e.g., washing with water or acetone, activation) can also influence sorbent properties, such as pore volume [5,84] and surface aliphatics [72].…”

Active research on biomass hydrothermal carbonization (HTC) continues to demonstrate its advantages over other thermochemical processes, in particular the interesting benefits that are associated with carbonaceous solid products, called hydrochar (HC). The areas of applications of HC range from biofuel to doped porous material for adsorption, energy storage, and catalysis. At the same time, intensive research has been aimed at better elucidating the process mechanisms and kinetics, and how the experimental variables (temperature, time, biomass load, feedstock composition, as well as their interactions) affect the distribution between phases and their composition. This review provides an analysis of the state of the art on HTC, mainly with regard to the effect of variables on the process, the associated kinetics, and the characteristics of the solid phase (HC), as well as some of the more studied applications so far. The focus is on research made over the last five years on these topics.

“…It also eliminates the need for an energy‐intensive drying before or during the process. This opens up the field of potential feedstock's to a variety of nontraditional sources: agricultural waste, wet animal manures, sewage sludge's, municipal solid waste (MSW), as well as aquaculture and algal residues . HTC process is an exothermal process that lowers both the oxygen and hydrogen content of the feed by mainly dehydration and decarboxylation.…”

Recently, the use of controlled release fertilizers in agriculture has resulted in huge benefits in plant growth and cultivation. Superabsorbent polymer (SAP)‐coated fertilizers have the added advantage in retaining water in soil after irrigation and also reduce the nutrient release rate from soil in a controlled manner. This study aimed to produce a nitrogen–phosphorus–potassium (NPK) fertilizer coated with superabsorbent carbonaceous microspheres polymer (SPC) by inverse suspension polymerization method with water‐retention and controlled release properties. Two sets of experiments were conducted: (1) three different weight percentages and (2) different materials. NPK coated with SPC showed increasing water‐retention ability with respect to carbon microsphere percentages and retains >80% water at the 30th day of experiment compared with pure NPK and NPK coated with SAP. The slow release behavior of all samples was investigated by induced coupled plasma mass spectrometry spectrometry and results showed that NPK coated with SAP and SPC has a low release rate with <50% nutrient release compared with uncoated NPK at the 30th day. The release mechanism kinetics of NPK coated with SAP and SPC were studied based on the Kosmeyer–Peppas model. The mechanisms approached Fickian diffusion‐controlled release as the n value for both samples was less than 0.5. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2020, 137, 48396.

This study focuses on determining the kinetic parameters of pyrolysis and gasification of manure‐derived hydrochar. Hydrochar was first pyrolyzed in Thermogravimetric analyzer at heating rates of 5, 10, and 20°C min−1 with N2 and gasified afterwards with CO2 at 800, 900, and 1000°C for 30, 60, and 90 min. Morphology of the pyrolysis and gasified chars were analyzed with FT‐IR and scanning electron microscope (SEM). Kissinger's method was used to evaluate kinetic parameters for pyrolysis, while Arrhenius method was implemented to evaluate gasification kinetic parameters. Activation energy for pyrolysis and gasification were 211.5 ± 7.7 kJ mol−1 and 270 ± 20 kJ mol−1, respectively. FT‐IR analysis revealed that ‐OH and aliphatic C‐H groups were significantly reduced compare to raw hydrochar during gasification. A decrease of particle size and an increase of amorphous region were observed in SEM analysis, while energy‐dispersive x‐ray spectroscopy analysis revealed an increase in oxygen and carbon contents in gasified char. © 2018 American Institute of Chemical Engineers Environ Prog, 38: 154–162, 2019
