Summary: The rapidly increasing global energy demand has led to the need for finding green, renewable, and sustainable alternative sources of energy. Bio-oil, derived from biomasses via liquefaction, is a promising candidate to replace fossil fuels. In this study, the thermal liquefaction of oak wood particles was carried out using different solvents, and the results showed that 1,4-dioxane yielded the highest bio-oil production.

Summary: This study reports hydrothermal liquefaction technology carried out on local Malaysian oil palm fronds to produce solid bio-char and liquid bio-oil. Observations showed that bio-oil yield percentage increased and bio-char yield percentage decreased with higher reaction temperature and time, leading to improved combustion properties of bio-char and bio-oil. Major chemical compounds identified in bio-oil by GC-MS were phenolic compounds and their derivatives, alcohols, ketones, and esters.

Summary: The selection of corrosion-resistant and cost-effective structural materials for biomass-derived oil production, upgrading, and storage has been extensively studied in our laboratory. The wide variety of biomass resources and liquefaction techniques result in products with diverse properties. This paper discusses the materials challenges in three distinct areas. Austenitic stainless steels have generally performed well in the production process at temperatures ranging from 350 to 550 degrees C, although issues such as thicker oxide scales and intergranular attack have been observed. For storage and transport of bio-oil products, organic acids present in the raw bio-oils can cause corrosion to carbon and low-alloy steels. Furthermore, certain subsequent processing methods can lead to corrosion of common austenitic stainless steels during exposure to sulfidizing gas at elevated temperatures. The study identifies cost-effective and sufficiently corrosion-resistant materials for each environment.

Summary: In this study, eXtreme Gradient Boosting was used to predict the bio-oil yield during solvothermal liquefaction of lignocellulosic biowaste. It was found that the prediction of the biomass conversion was crucial in establishing an accurate model. By combining the contents of biochemical components and operating factors, the best prediction for the biomass conversion was achieved. Introduction of the biomass conversion as an input improved the prediction accuracy of bio-oil yield. The best prediction models were explained using game theory-based feature importance and partial dependence plotting analysis, shedding light on biomass conversion pathways and bio-oil generation mechanism.

Summary: Global energy demand and environmental concerns have led to a growing emphasis on fuel production from renewable resources. Microalgae offer an attractive alternative carbon source. This study investigated the hydroconversion of bio-oil derived from hydrothermal liquefaction of microalgae using supported catalysts. NiW sulfide catalysts proved to be the most efficient, producing a hydrotreated oil with superior properties. The results suggest that different catalysts promote different reaction pathways, contributing to the conversion of refractory compounds.

Summary: Liquefaction is an attractive technology for converting biomass into bio-oil without drying the feedstock, and is conducted at relatively low temperatures. Co-liquefaction of different biomass feedstocks can enhance the liquefaction degree and chemical properties of the resulting bio-oil. Understanding the interaction during co-liquefaction process is important for tuning the chemical species and yield of the bio-oil. Operational parameters and mixing ratios of different biomasses also play a significant role in the co-liquefaction behavior.

Summary: Random Forest (RF) and eXtreme Gradient Boosting (XGB) methods were used to predict the yield (Yb) and nitrogen content (Nb) of bio-oil from solvothermal liquefaction of algal biomass. XGB provided superior models with R2 and RMSE of (81.61% and 8.08 wt%) and (93.33%, 0.6 wt%) for Yb and Nb, respectively. The study highlighted the importance of the solvent's hydrogen-bonding donor strength in predicting Yb and Nb.

Summary: This article presents a magnetite supported on activated carbon catalyst that can be magnetically retrieved and reused without regeneration. The FeOx/C catalyst increased the bio-oil yield by 19.7 +/- 0.96% in the HTL of draff reaction. The use of homogeneous Na2CO3 base as a catalyst and co-catalyst improved carbon extraction into the aqueous phase. The exceptional catalytic activity is attributed to the Fe3O4 phase, which enhances biomass decomposition and oil property with an energy recovery of about 84%.

Summary: This study proposed a conceptual biomass liquefaction system with supercritical water for combined production of biooil, power, and heating. Through thermodynamic and life cycle environmental assessments, it was shown that the system can achieve high energy and exergy efficiency, with potential benefits compared to other biomass-based systems. Environmental assessment also revealed lower environmental impact values for this system, especially when carbon capture and wastewater treatment units are applied. The comparison of thermodynamic and environmental performance among different biomass-based energy conversion systems indicates that biomass liquefaction with supercritical water is a relatively efficient and clean technology for producing carbon-neutral bio-oil.

Summary: In this work, a techno-economic analysis is conducted for an integrated torrefaction and pelleting process, which produces torrefied rice straw pellets in a single-step process. The proposed process eliminates the need for an external binder, as the pelleting and torrefaction steps are merged and the lignin naturally present in the biomass acts as the binder. The techno-economic assessment shows that a briquetting process with a production capacity of 30,000 tons per year could be highly profitable, with a ROI of 30%, payout time of 2.4 years, and break-even point of 42% at a selling price of $73 per ton.

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.
