“…Nut shells and bamboo are inexpensive wastes that have natural adsorption characteristics and can be used as precursors for producing activated carbon [28,29]. Pecan shells and bamboo chips were collected from a market in Hangzhou City (Zhejiang Province, China) and pulverized using a high-speed crusher to serve as raw biochar materials.…”

Pyraclostrobin is a potent extensive-spectrum fungicide widely used in agricultural production but poses a substantial threat to aquatic life. Therefore, there is an urgent need to remove pyraclostrobin from the ecological environment. This study reports the adsorption of pyraclostrobin in water using pecan-shell biochar, bamboo biochar, and their deashing products. The kinetics and isotherms indicate that the pseudo-second-order kinetics and Freundlich model are the most suitable for both types of biochar. The thermodynamic results demonstrate that the adsorption process of biochar is spontaneous and exothermic. Combined with characterization and factor analysis experiments, it is revealed that the adsorption of pyraclostrobin on biochar is attributed to various mechanisms, including pore filling, hydrophobic interactions, π-π and p-π interactions, and hydrogen bonding. At the initial concentration of 0.5 mg·L−1, the adsorption rates of pyraclostrobin of the four biochar samples (<0.075 mm) reached 67–80% within 5 min. These findings suggest that both pecan-shell and bamboo biochars are efficient pyraclostrobin adsorbents, with the former showing better outcomes. There is still an adsorption rate of >97% after 5 cycles of adsorption by two types of biochars. Deashing significantly enhances the adsorption efficiency of pecan biochar, but it has an insignificant effect on bamboo biochar. This study will aid in the selection of cost-effective and ecofriendly adsorbents to reduce the environmental risk associated with pyraclostrobin.

“…The BB-C2 sample has a less rough or cracked outside surface, as seen in Figures 11(a) and 11(a-1), due to less fluctuation of temperature while slow low heating rates occurred (Ong et al, 2021;Zhang et al, 2020) during the pyrolysis process of the stove, and heat is likely to transfer through the longitudinal direction rather than in the radius direction of bamboo wood chunks (Kalderis et al, 2023;Pinisakul et al, 2023). However, increasing pyrolysis temperature results in improved total surface and pore volumes of biochar (Binh et al, 2022;Hettithanthri et al, 2023;Faraji et al, 2023), but a thinner wall of the pore was found due to the decomposition of hemicellulose, cellulose, and lignin with increased temperature (Figures 11b and 11b-1).…”

The global demand for biochar in agricultural and carbon sequestration applications is increasing; nevertheless, biochar production using the 50-liter household biomass gasifier stove (50L-HBGS) in Thailand found major issues that need to be improved. The objective of this study was to study the effects of the airflow in the non-uniform combustion core shape (NCCS) on the biochar production characteristic of the 50L-HBGS. The new design of the NCCS was constructed and studied to replace the existing combustion core shape (ECCS) at Mahasarakham University. The height, air inlet, and air outlet diameters of the NCCS were designed at 45, 24, and 11.4 cm, respectively. The NCCS with 21 holes of the pyrolysis gas outlet, a diameter of 4 mm for each, was integrated into the 50L-HBGS and performed comparative tests to the ECCS using 9 kg of bamboo wood chunks in three consecutive experiments. The airflow and the combustion behavior were studied through the stove temperature profiles, which were recorded every 5 minutes using a digital data logger. The biochar products were studied using the scanning electron microscope (SEM) with the energy dispersive x-ray spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR), and the proximate analysis technique. The study indicated that the 50L-HBGS with the NCCS made significantly improved the airflow rates in the combustion core, resulting in better continuous burning during the ignition state than with the ECCS. Moreover, the pyrolysis temperatures were significantly improved, it was provided temperatures during the pyrolysis process reached higher than 500 oC, resulting in the liquid tar being removed and no unburned wood chunks remaining at the end. The characterization result demonstrated that the 50L-HBGS with the NCCS had created biochar within a range of micropore and macrospore sizes and high fixed carbon content, which could be advantageously used for different agricultural and carbon sequestration applications.

This work investigates the synthesis of M-oxides (M = aluminum, iron, magnesium, zinc) supported on charcoal by wet impregnation and using these materials in removing nitrate from water. On the one hand, it studies the incorporation of the solid and the modification that the carbonaceous support undergoes, and on the other hand, it investigates the performance of the material produced in the synthesis compared to charcoal acting as a control group. In the first part, the incorporation of the solid material was characterized structurally (SEM, Hg porosimetry) and compositionally (XRD, elemental analysis), and the modification of the carbonaceous support was characterized by the yield and the amount of solid incorporated in the synthesis product (TGA). The results show that the synthesis by wet impregnation produces a composite material formed by a porous matrix of carbon-containing solid in an amount, with a distribution and precursor-dependent crystallinity. The synthesis also results in the loss of a significant amount of carbonaceous support, which varies from precursor to precursor. The results also show that only the material with zinc oxide outperforms the material with no added solid in removing nitrate from water. Finally, this work´s results show that wet impregnation allows obtaining materials that improve the ability to remove nitrate from water. However, they show that the carbonaceous support undergoes a significant change whose influence on nitrate removal remains unknown.
