Gas‐Phase Hydrodeoxygenation of m‐Cresol Using Isopropanol as Hydrogen Donor Over a Ni‐Supported Catalyst

ChemCatChem, Volume 18, Issue 11, 15 June 2026.
Continuous‐flow hydrodeoxygenation of m‐cresol assisted by catalytic transfer hydrogenation (CTH‐HDO) was carried out at 300°C and atmospheric pressure over a Ni/SBA‐15 catalyst, using isopropanol as a renewable hydrogen donor. Under optimized conditions, a toluene selectivity of 56% was achieved, highlighting the potential of this approach as a safer ...

Benchtop NMR Spectroscopy of Pyrolysis Oils From Mixed Plastic Waste: Parameter Optimization for Oil Characterization and Detection of Heteroatom‐Containing Compounds

Chemistry–Methods, Volume 6, Issue 6, June 2026.
In this article, benchtop‐NMR spectroscopy was evaluated as an analytical method for the characterization of plastic waste derived pyrolysis oils. The signal‐to‐noise ratio was enhanced via measurement parameter optimization and optimization of postacquisition parameters.

Hydrotreatment of Nylon 66 and Amide Model Compounds Over Sulfided NiMo Catalysts

ChemCatChem, Volume 18, Issue 9, 14 May 2026.
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.
