Tequila vinasses are organic wastes generated during ethanol fermentation at elevated temperatures (≥90 °C) and pH ≤ 4.0, making them hazardous to the environment. This paper describes a new, simplified UV–vis spectroscopy-based procedure for monitoring adsorption of color compounds in tequila onto silica-based adsorbents, along with an optimized synthesis method produce most efficient sol–gel synthesized thiol-functionalized adsorbent. Under conditions, uptake capacity this adsorbent reaches 0.8 g g−1 90 min. Experimental results demonstrate that has specific affinity melanoidin-type molecules. The demonstrates excellent thermal stability (~316 °C). work indicate possesses potential treatment from wastewater discharges.

In this paper, alumina-modified wood liquefaction (AL-WP) was prepared by blending nano-alumina (Al2O3) into phenolic resin (WP) using a co-blending method. Alumina-modified protofilament fiber (AL-WPF) obtained melt-spinning, curing, and thermo-curing processes, which were followed carbonization to obtain carbon (AL-WCF). This paper focuses on the enhancement effect of doping mechanical properties heat resistance (WCF), explores evolution graphite microcrystalline structure during high-temperature process, optimizes curing conditions AL-WPF. The results showed that introduction Al2O3 significantly improved fibers. When 1.5% doped carbonized at 1000 °C, tensile strength AL-WCF increased from 33.78 MPa 95.74 MPa, there an 183%, its residual rate could reach 79.2%, better than undoped it exhibited more substantial heat-resistant property. addition, best process for alumina nanoparticle liquefiers optimizing conditions: hydrochloric acid concentration 16%, formaldehyde 18.5%, temperature increase 15 °C/min, holding time 3 h, 100 °C. These studies provide theoretical basis technical support developing applying fibers liquefiers.

Climate change demands urgent action to limit greenhouse gas (GHG) emissions and explore methods for atmospheric carbon removal. Forest residues, a significant biomass resource, represent readily available solution. With the use of life cycle assessment (LCA), this study investigates environmental advantages thermochemical processes utilizing forest residues produce valuable energy-dense products, like syngas, bio-oil, biochar, providing sink. While slow pyrolysis emphasizes biochar production sequestration, gasification focuses on bioenergy generation. This research evaluates performance both techniques in terms sequestration GHG mitigation. comprehensive analysis aims identify critical factors influencing sustainability management. The findings aim contribute achieving sustainable development goals by highlighting mitigating climate change.

In this thesis, wood loaded with a silica–titanium (Si-Ti) composite film was prepared using the sol–gel method in order to achieve improved high hydrophobicity and photocatalytic activity under visible light. The factors affecting structure properties of film, as well optimization process, were discussed.

Furthermore, -NO3, enhanced higher dosage nitric acid. Conversely, -OH decreased drying temperature. XRD showed acid could promote transformation TiO2 from amorphous anatase, while SiO2 would reduce grain size anatase growth rutile TiO2. surfaces Si-Ti changed hydrophilic hydrophobic, significant differences observed between different levels each factor. surface-loaded films on most affected by amount acid, which influenced crystallinity thus impacted activity. changes VTES not only crystalline phase but through generating SiO2. Finally, based optimal preparation process (titanium–alcohol ratio 1:5, titanium–silicon 1:0.2, titanium–acid 1:0.5, temperature 100 °C), achieved contact angle up 125.9° exhibited decolorization rate for rhodamine B UV light reaching 94% within 180 min.
