Summary: This study aimed to analyze the two-step pyrolysis process, focusing on the redistribution of mass, elements, and energy. The results showed that torrefaction pretreatment increased biochar yield and decreased bio-oil yield, but enhanced the quality of bio-oil. Most of the carbon remained in the feedstock after torrefaction, while oxygen and hydrogen were transferred into the torrefaction liquid and non-condensable gases. Therefore, torrefaction prior to fast pyrolysis is recommended, with 260°C as a suitable temperature.

Summary: Through the study, it was found that the activation energy for biomass samples varied significantly in different conversion ranges, and the frequency factor values also varied within the same conversion ranges for different samples. The average change in Gibbs free energy for the pyrolysis of pinewood sawdust and sugarcane bagasse was 207.5 and 205.8 kJ/mol, respectively. The difference between activation energy and enthalpy for the pyrolysis of both biomass samples was approximately 5.5 kJ/mol, indicating favorable product formation with considerable bioenergy potential.

Summary: This study systematically explored the regulation of secondary reactions during the pyrolysis of sugarcane bagasse by adjusting the pyrolysis temperature and H2SO4 loading. It was found that reducing the pyrolysis temperature suppressed both primary and secondary reactions, while adjusting H2SO4 loading promoted primary depolymerization reactions and secondary dehydration reactions. These findings demonstrate the capability of adjusting H2SO4 loading to regulate primary and secondary reactions during biomass pyrolysis at low temperatures and enable product switching.

Summary: This study attempted to use biomass as an energy source, specifically focusing on the pyrolysis of sugarcane bagasse with and without a catalyst. The presence of the catalyst led to a higher content of hydrocarbons in the bio-oil. Thermal analysis revealed a four-stage weight loss profile, and different methods were used to determine the activation energy values. The results indicated that the catalyst lowered the activation energy for the decomposition of hemicellulose, cellulose, and lignin, enhancing the quality of the oil produced.

Summary: A new N-doped biochar (NSB) was prepared by one-pot pyrolysis using sugarcane bagasse, melamine, and NaHCO3 as feedstock, nitrogen source, and pore-forming agent, respectively. The physicochemical properties of NSB were characterized by SEM, EDS, XRD, FTIR, XPS, and BET analyses, confirming its excellent pore structure, high specific surface area, and nitrogenous functional groups. The optimized conditions for CIP adsorption by NSB were determined, and a CIP adsorption capacity of 212 mg/g was achieved under these conditions. The adsorption mechanism involved pore filling, 7C-7C conjugation, and hydrogen bonding. This study demonstrates the reliable technology of using low-cost NSB for the treatment of CIP wastewater.

Summary: Biodiesel production has increasingly shifted towards using heterogeneous catalysts derived from biomass, due to their sustainability, economical and eco-friendly nature, ease of recovery, and the potential to eliminate biomass residues. The review discusses various biomass sources as precursors for heterogeneous catalysts, different methods for preparation, their advantages and drawbacks, as well as their performance in biodiesel production. The use of biomass ash or biochar-based catalysts shows promise in biodiesel synthesis, but requires improvements in catalyst load, reaction time, temperature, and methanol-to-oil ratio.

Summary: This study comprehensively reviews the technical problems associated with the utilization of sugarcane trash (SCT) in bioenergy plants in Cuba. The best approach identified is to leave 50% of the SCT in the field and take the remaining 50% to the factory for dry cleaning. The use of vibratory roller systems and pneumatic cleaning is found to be the most effective for SCT separation. Additionally, biological pretreatments show promise in degrading lignin and hemicellulose in SCT.

Summary: Pyrolysis liquids are difficult to analyze comprehensively due to their complex and heterogeneous composition. The use of two-dimensional 1H-13C heteronuclear single-quantum correlation (HSQC) nuclear magnetic resonance (NMR) has gained renewed interest for quantitative recording, providing a valuable tool for fingerprinting and assessing these complex liquids. However, data analysis of 1H-13C HSQC spectra has been lacking behind recent experimental developments. This study explores and demonstrates a new approach for automated data analysis from 1H-13C HSQC spectra using image processing tools.

Summary: This study investigates the effect of citric acid leaching on the quality and stability of fast pyrolysis bio-oils from sugarcane bagasse and sugarcane trash. The results show that citric acid leaching does not improve the fuel-related properties of bio-oil, but it does increase the concentration of levoglucosan and decrease the concentration of carboxylic acids and phenols. The study concludes that optimized biomass demineralization pretreatment with citric acid can produce bio-oil with high yield and rich in high-value chemical compounds. However, it does not necessarily improve the quality and stability of the bio-oil for fuel purposes.

Summary: Gasification kinetics of six chars from residual origin were studied under relatively low temperature, low CO2, and high H2O partial pressures. The Random Pore Model (RPM) showed the best fit to experimental results, but the selection of the reaction model depended on the ash composition, specifically the presence of alkali and alkaline earth metals. Chars with ash content higher than 30% wt. were modeled with the RPM model, while chars with the highest K/Si ratio required modified versions of the RPM to accurately predict reaction rates. Textural properties played a key role in determining reaction parameters, such as the pre-exponential factor and activation energy, for chars with similar ash content and composition.
