Summary: Bio-oil from biomass pyrolysis has potential as a sustainable biofuel and high-value-added chemical. However, it suffers from corrosiveness, low HHV, and instability due to high acid, water, and oxygenate content. This study investigates the refining of bio-oil using natural zeolite-based transition metal oxide through the hydrodeoxygenation method. The results show improved physicochemical properties and high catalytic performance, indicating its potential for better and low-cost biofuel production.

Summary: The research found that high acidity is beneficial for demethylation, while medium acidity may promote the cleavage of the aromatic-OCH3 bond. The higher the titania content, the stronger the catalyst's ability to produce completely deoxygenated compounds.

Summary: In this study, the catalytic activity of Ni catalysts in the decarboxylation/decarbonylation of triglycerides to hydrocarbons was improved by employing Pd as a promoter and using multifunctional supports. Pd addition promoted Ni reduction, leading to an increase in the number of active sites. The use of SiO2-Al2O3 as a support further enhanced the catalyst performance by promoting Ni reduction, as well as providing a high surface area and strong acidity.

Summary: By using hierarchical nanosponge ZSM-5 supporting Ni catalyst, the effect of volumes and substituents on phenolics is explored. The Ni/NPZ catalyst with hierarchical pores and highly dispersed metal species shows enhanced adsorption of phenolics and adsorption/transfer of hydrogen, resulting in higher catalytic activity than the reference micropores catalyst Ni/CZ. Phenolics with large volumes such as 4-propylphenol exhibit lower conversion rates than phenol and anisole through sequenced hydrogenation and deoxygenation procedures. Deoxygenation occurs first on guaiacol and 2,6-dimethoxyphenol due to steric resistance, followed by hydrogenation of aromatic rings. Interestingly, the scission of C-C bonds occurs at 2,6-ditertbutylphenol by electron transfer between tertbutyl and aromatic ring, improving their initial conversion.

Summary: Selective hydrodeoxygenation (HDO) of phenolic compounds derived from pyrolysis lignin-oil is a promising route for high-value utilization of biomass-derived products. In this study, an optimized Co/1 K-Al2O3 catalyst achieved high conversion and selectivity in the HDO of guaiacol. Highly dispersed Co particles provided more active sites and improved the chemisorption of guaiacol molecules, enhancing HDO activity. Doping K species into the Al2O3 support resulted in decreased acid sites and eliminated strong acid sites, preventing unwanted conversion of cyclohexanol to byproduct cyclohexane. Proper acid sites and strength maximized the selectivity of cyclohexanol during selective HDO of guaiacol. Additionally, good alkyl cyclohexanol selectivities were observed in selective HDO reactions using other phenols as substrates with Co/1 K-Al2O3 catalyst.

Summary: An emerging synthetic route for the co-synthesis of dimethyl oxalate (DMO) and dimethyl carbonate (DMC) via the indirect oxidative carbonylation of CH3OH is presented. The catalytic performance strongly depended on the catalyst activation, as the heat treatment could tune the silanols around the Pd species on the silicalite-1 zeolite. The best performing catalyst had an average Pd nanoparticle size of 3.2 nm and Pd loading of 0.48 wt%, showing high stability for at least 200 h.

Summary: Two nickel alumina catalysts were synthesized by different methods and evaluated for their catalytic efficiency in the transformation of sunflower oil into green diesel. The catalyst prepared by co-precipitation showed higher efficiency due to its higher specific surface area and smaller nickel nanoparticle size compared to the catalyst prepared by wet impregnation. Increasing the activation temperature resulted in larger nickel nanoparticles and decreased catalytic efficiency. The optimized reaction conditions achieved complete transformation of sunflower oil and waste cooking oil into green diesel with high yield.

Summary: This study investigates the dry reforming of methane (DRM) through experimental and computational methods. The catalyst used, NiOx/ZeoA, was synthesized by functionalizing nickel salt with oxalate ligand to ensure highly downsized Ni nanoparticles interaction with zeolite A support (ZeoA). The presence of in situ sodium atoms increases the catalyst basicity, facilitating CO2 activation. The computational results show that isomorphic substitution of Al and Si atoms with Ni atoms narrows the bandgap and excites Ni's 3d electrons into the conduction band. The addition of Ni reduces the intensity of negative charges on O atoms. This catalyst demonstrates high CO2 and methane activation with stability and resistance to carbon deposition.
