Summary: The characteristics of bio-oil derived from soybean meal were improved through hydrodeoxygenation using monometallic and bimetallic catalysts. The oxygen content was reduced and the heating value of the bio-oil increased. The Ni/gamma-Al2O3 catalyst was found to be more effective in reducing oxygen content and increasing the heating value.

Summary: In this study, the influence of reaction parameters (temperature, holding time, and biooil concentration) on the upgrading of esterified CG-BO over MgNiMo/AC catalyst in supercritical ethanol was investigated. The MgNiMo/AC catalyst played a crucial role in hydrogen production and hydrodeoxygenation reactions of CG-EBO during the supercritical upgrading. The optimized conditions for the upgrading process were determined as 375 degrees C, 2 h holding time, and 20 wt% CG-EBO concentration, which resulted in a biofuel product with high yield and low oxygen content.

Summary: Biomass-to-liquid thermochemical routes, such as fast pyrolysis, are promising methods for converting waste biomass into sustainable hydrocarbon fuels. However, the bio-oil derived from pyrolysis has poor quality and requires extensive upgrading before it can be used as a jet fuel. Catalytic cracking and hydrodeoxygenation are the most promising approaches for upgrading bio-oil to bio-jet fuel. Further research is needed to understand the mechanistic aspects of raw bio-oil upgrading.

Summary: Fast pyrolysis and hydrothermal liquefaction are considered promising technologies for liquid bio-fuel production, but the poor quality of crude bio-oils has limited their direct applications. Hydrotreatment such as hydrodeoxygenation is a common upgrading technique, and this review explores the effects of different reaction conditions on the HDO treatment of real bio-oil. The underlying mechanisms for bio-oil HDO, technical challenges, and potential solutions are discussed, along with knowledge gaps and future research directions.

Summary: The quality of bio-oil produced from oil palm fronds was enhanced through esterification pre-treatment and hydrodeoxygenation reaction. The catalyst used in the reaction was mixed metal oxide anchored within zeolite mordenite. The presence of metal oxides on the catalyst's surface increased its activity in producing liquid products and reducing coke formation. Upgrading the bio-oil improved its physicochemical properties compared to the one-stage upgrading process.

Summary: This study proposes a controllable synthesis method for Ni-Mo catalysts using multi-wall carbon nanotubes as supports. The results show that Ni improves the formation of beta-Mo2C and enhances the hydrogenation and hydrodeoxygenation activities of the catalysts towards benzofuran. The synergistic interaction between Ni and Mo is maximized at a Ni/Mo molar ratio of 0.3.

Summary: This study investigated the hydrodeoxygenation of acetone using different catalysts, with the results showing that the 5% Ni2P/HZSM-5 catalyst favored the formation of acetaldehyde and methyl isobutyl ketone at lower temperatures, while higher temperatures increased the proportion of aromatic hydrocarbons. Optimal conditions using this catalyst gave a selectivity of 49% for aromatics (benzene, toluene, and xylene).

Summary: A copper catalyst modified with propanoic acid was developed for the hydrodeoxygenation (HDO) of crude lignin bio-oil to jet fuel precursors. The modified catalyst exhibited exceptional catalytic performance, improving the yield of jet fuel precursors and reducing the double bond equivalence and aromaticity index of the products. These findings suggest promising avenues for increasing the efficiency of heterogeneous catalysts in the conversion of lignin-based bio-oil to alternative fuels.

Summary: The study showed that co-processing deoxygenated pyrolysis bio-oil with vacuum gas oil did not significantly impact baseline hydrocracking selectivity under fixed reaction temperatures, but led to increased hydrogen consumption with higher bio-oil content. Additionally, differences in hydrocarbon composition and fuel properties were observed in the liquid products from different bio-oil blends after co-processing.

Summary: This study explored the pyrolysis behaviors and mechanisms of different monosaccharides, including arabinose, galactose, galacturonic acid, and glucuronic acid. The roles of structural differences in these monosaccharides were analyzed, and it was found that glucuronic acid undergoes a special C-C bond breaking reaction during pyrolysis. The findings provide a deep understanding of the pyrolysis chemistry of hemicellulose and the role of different branches.
