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: This study successfully removes oxygen atoms from a lignin-derived monomer (guaiacol) using nonthermal plasma, improving the heating value and thermal stability of biomass-derived bio-oils. The research proposes a product selection mechanism and analyzes the correlation between mean electron energy and product distribution, providing important guidance for the practical application of plasma-enabled bio-oil conversion.

Summary: This study focuses on the upgrading of biomass-derived bio-oil through catalytic hydrogenation. A new catalyst, Rh/ZrO2, was developed with high deoxygenation ability. Catalytic hydrogenation can remove oxygen from bio-oil and reduce its oxygen content, thereby enhancing its potential as a biofuel.

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 high acidity, oxygen and water contents in fast pyrolysis oil necessitate further upgrading for improved fuel properties, such as catalytic hydrodeoxygenation (HDO). Nb2O5 was evaluated as a support for Pd-based catalysts in this process, showing enhanced activity towards hydrogenolysis and hydrogenation compared to SiO2. Iron as a promoter also improved hydrogenation and hydrogenolysis, leading to higher deoxygenation degree and product HHV.

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: In this study, an acid-modified vermiculite (AVM)-supported Pd-Ni bimetallic catalyst was investigated for the hydrodeoxygenation of bio-oil and its model compounds. The catalyst efficiently hydrodeoxygenated phenol, reaching 94% conversion at 0.5% Ni loading and temperatures beyond 513 K. The synergistic effects between the active component and the carrier were found to be the main reason for the catalytic activity, with significant influences of Ni loading and temperature on the hydrogenation of phenol.

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: A novel two-stage solvent-assisted batch catalytic hydroprocessing method was developed to upgrade intermediate pyrolysis bio-oil to produce blended liquid fuels with approximately 23 wt% hydrocarbon-rich biofuel content. The first stage reactions involving mixtures of dodecane and bio-oil, hydrogen gas, and metal-supported catalysts suppressed char formation and obtained up to 80 wt% liquid organic products dominated by ketones and phenols. The second stage reactions with the first stage organic liquid products gave over 90 wt% of blended liquid fuel. Pt/Al2O3 catalyst deactivated in the first stage but remained stable in the second stage.

Summary: This study developed a nanocellulose/chitosan-based film coated with polylactic acid (PLA) to monitor beef spoilage in real-time. The film displayed a visible color change in response to pH buffer solutions and showed an apparent color change after 5 days as a threshold for beef spoilage. Colorimetric device processing revealed substantial color difference values after 5 days of beef spoilage.
