“…The decrease in peak intensity indicates that the hydroxyl group almost disappeared after torrefaction. This was due to loss of water in torrefied biomass [36][37][38]. The adsorption of C−H bond at 2909 cm −1 also weakened.…”

Today, torrefaction is important technique for extending the potential of biomass for improvement of energy density. The independent variables investigated for torrefaction study were temperature, retention time, acid concentration, and particle size. The experiment was designed by central composite design (CCD) method using design expert (version 11). The three dependent variables were higher heating value (HHV), energy enhancement factor (EEF), and mass yield (MY) were carried out. Numerical optimization using response surface method (RSM) to maximize the HHV and EEF with lowest MY was carried out. The maximum HHV of 25.05MJ/kg, lowest MY of 60.15%wt and highest EEF of 1.593 were obtained at 299.99°C, 31.89min of retention time, 0.75g/l of acid concentration and 0.20mm of particle size. Proximate analysis, bulk density, hydrophobicity, energy density, and ultimate analysis of raw and torrefied biomass were determined to analyze the physiochemical properties of the fuel. In addition, thermo-gravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), and X-ray diffractometer (XRD) were done to distinguish the behavior of raw and torrefied wheat straw. The results implied that energy density of torrefied biomass was well improved when compared with raw biomass. All in all, energy density of torrefied biomass was improved, which can be used as an alternative energy.

“…As a result, biochar produced through low-temperature pyrolysis of biomass exhibits improved adsorption properties. Changes in the surface properties (Jiang et al 2021), electrochemical characteristics, and π-π electron donor-acceptor interactions of biochar further impact its adsorption efficiency (Klupfel et al 2014;Sorrenti et al 2016;Zhao and Zhou 2019).…”

The global environmental issue of soil contamination with antibiotic-resistance genes has garnered increased attention in recent years due to its impact on ecosystems and human health. Despite this recognition, researchers face challenges in comprehensively understanding the mechanisms underlying the production and dissemination of soil resistance genes, particularly in relation to their implications for human health. This lack of understanding poses a barrier to the development of effective and precise control strategies. Biochar, a sustainable material, exhibits favorable adsorption properties characterized by its large pores and specific surface area. Therefore, we propose to explore the potential application of biochar addition in soil resistance gene management. In order to establish a solid research foundation in this area, in this paper we review the mechanisms underlying the generation and accumulation of soil resistance genes over the last decade, along with their transmission pathways and interfacial interactions. Biochar may help repair soil resistance genes by affecting factors like antibiotic levels, environmental conditions, enzymatic activity, and gene migration mechanisms, opening up new research possibilities.
