Summary: The study demonstrates that pyrolysis of Delonix regia and butyl rubber tube waste at 600 degrees C and 1 bar pressure can produce high-quality bio-oil and bio-char. The highest HHV of bio-oil occurs at a DR/TW ratio of 50:50, with the bio-oil mainly consisting of aliphatic and aromatic compounds.

Summary: In this study, the abandoned epoxy resin matrix in composite wastes was pyrolyzed into epoxy resin pyrolytic oil (EPO) and analyzed. The results showed that more than half of the epoxy resin matrix was converted into EPO, mainly consisting of phenol and its derivatives. CF reinforced EPOF composites with comparable strength and ablation rates to CF/PF composites were successfully fabricated, thanks to the good process performance of the EPOF prepolymer.

Summary: Phosphorylated cellulose nanofiber (CNF) is a newly emerged CNF with high functionality, containing monophosphate, polyphosphate, and cross-linked phosphate groups. The phosphorylation process is regioselective at the C2 and C6 positions, with no significant difference in surface degrees of substitution.

Summary: Research on combustion engine applications for tyre pyrolysis oil (TPO) is abundant worldwide, but the role of TPO as a fuel for transport applications remains uncertain due to conflicting or ambiguous results. A critical review of over 200 influential research papers suggests that TPO may have potential as a fuel component in marine, off-road, and heavy-duty road applications.

Summary: The addition of an appropriate amount of water vapor during coal carbonization process improves the combustion performance and fixed carbon proportion of semicoke, but excessive water vapor inhibits the enhancement of physicochemical properties. Avoiding the entry of excess water vapor into the high-temperature pyrolysis section during coke quenching is crucial for maintaining the performance of semicoke.

Summary: The conversion of waste tires into value-added products such as bio-fuels is recommended for better waste management. This study investigates the catalytic-hydrocracking of waste tire pyrolytic oil to fuels using Ni-W supported on zeolite X and A. The results show that the prepared catalysts exhibit high activity in producing gasoline and diesel from the waste tire pyrolytic oil.

Summary: Eucalyptus globulus sawdust, a residue from the pulp and paper industry, can be recycled through thermochemical liquefaction to produce bio-oil. The aqueous extract of the bio-oil contains carbohydrates, particularly fructose and glucose, which can be used in the industry to produce sustainable materials. The sugar composition of the aqueous extract was identified and quantified using analytical techniques such as HPLC, HSQC-NMR, FTIR-ATR, and elemental analysis.

Summary: This study explores the potential of water-soluble fractions and their combination with nanobentonite for wood protection. The water-soluble fractions significantly affect the water repellency and antifungal activity of wood, while the addition of nanobentonite further enhances the protective effect.

Summary: In this study, a co-pyrolysis strategy was proposed to convert bio-oil distillation sludge (DS) into syngas efficiently. The results showed that rapeseed cake (RC) had a higher gasification reactivity compared to DS, indicating its potential to enhance the biochar reactivity of DS. The ordered arrangement of crystallites in DS char hindered the gasification reaction, while the large amounts of amorphous carbons and defects in RC char promoted its reactivity. Additionally, machine learning algorithm was utilized to predict the co-gasification behaviors, showing promising results.

Summary: The determination of the abundances of CHx, C = O, and aromatic groups in chondritic Insoluble Organic Matter (IOM) and coals by Infrared (IR) spectroscopy was carried out in this study. A calibration approach based on a C-13 synthetic model material was used, and the ratios of the cross-sections of these groups were determined. The study found discrepancies in the estimation of aliphatic to aromatic carbon and aliphatic to carbonyl ratio, possibly due to the control of absorption cross-section by the local molecular environment. In coals, the integrated cross-section ratio varied with vitrinite reflectance, with local oxygen speciation playing a critical role in this variation.

Summary: This study investigates the effects of nutrient stressing on the yield and quality of bio-oil produced from microalgae thermal conversion. The results show that nutrient stressing can enhance the bio-oil yield and improve its quality. Additionally, a predictive model based on artificial neural network is developed for bio-oil yield prediction.

Summary: This study applied the pyrolysis method to treat oil-contaminated soil and measured the removal efficiency of main pollutants. It also investigated the effects of temperature, treatment time, and moisture content on pyrolysis efficiency. The integrated ecotoxicity of the treated soil was evaluated using Daphnia magna and Allivibrio fischeri. Results showed that higher treatment temperatures, moisture content, and treatment times led to higher pyrolysis efficiency. The toxicity of the soil was reduced by 99% after pyrolysis, and the assessment of toxicity was more sensitive in Allivibrio fischeri than in Daphnia magna.
