Catalytic upgrading of hydrothermal liquefaction biocrudes: Different challenges for different feedstocks [PDF]
Hydrothermal liquefaction (HTL) followed by catalytic hydrotreating of the produced biocrude is increasingly gaining ground as an effective technology for the conversion of biomass into liquid biofuels.

Mechanochemical Hydrodeoxygenations
A silver‐catalyzed mechanochemical hydrodeoxygenation with triethylsilane as reductant allows to convert ketones to the corresponding methylene derivatives in good yields after a short reaction time. Selected examples show that also alcohols, ethers, and sulfoxides can react. In this work, a mechanochemical hydrodeoxygenation (HDO) was developed. Using

Role of Mo in catalysts based on noble metals in hydrodeoxygenation reactions [PDF]
The use of bio-energy as a renewable alternative to fossil fuels is nowadays attracting more and more attention. The bio-fuel from biomass seems to be a potential energy substitute for fossil fuels since it is a renewable resource that could contribute ...

Catalytic Conversion of Lower Olefins to Aromatics Using Zeolite‐Based Catalysts
Zeolite‐catalyzed upgrading of light olefins (C2–C4) into benzene, toluene, and xylenes (BTX) represents a sustainable route to aromatics. This review outlines thermodynamic and mechanistic aspects, the influence of acidity and textural properties of catalysts.

Hydrotreatment of Nylon 66 and Amide Model Compounds Over Sulfided NiMo Catalysts
Hydrotreatment of nylon‐66 and the model amide N,N‐dibutylhexanediamide over sulfided NiMo/Al2O3 reveals competing hydrodenitrogenation and hydrodeoxygenation pathways, without formation of heterocyclic products. Pathway selectivity is influenced by reaction conditions and differs between the model compound and the real nylon sample.

Transitioning of the Chemical Industry Toward a Net‐Zero Carbon Dioxide Emission Path
One way to reduce the greenhouse gas footprint of the chemical industry to almost zero would be the production of the platform molecules C1‐compounds, olefins, aromatics, and ammonia by non‐fossil pathways. The rest of the chemical production chains could be essentially left unchanged, provided the process energy input is renewable.

Heterogeneous catalysis has historically been developed in the gas phase, however, we have found it pertinent to highlight solvent effects that must be accounted for in liquid environments. Condensed phase catalysis, like that in biomass, petroleum and the conversion of CO2, stands to benefit from the typically overlooked discussion regarding the ...

Vanillin Hydrodeoxygenation: Kinetic Modelling and Solvent Effect
Vanillin hydrodeoxygenation was investigated using Pt/C catalyst in the temperature and total pressure ranges of 80–200 °C and 20–30 bar in several solvents, such as tetrahydrofuran, 2-propanol, water and in solventless conditions using 1:1 mass ratio of vanillin to guaiacol. The results revealed that the rate increased with increasing solvent polarity
