Decomposition Mechanisms of Lignin-Related Aromatic Monomers in Solution Plasma

Plasma
Lignin is a natural aromatic macromolecule present in wood and an abundant resource on Earth, yet it is hardly used. In this study, an aqueous solution plasma treatment was investigated for the catalyst-free production of valuable chemicals from lignin ...

Performance of sulfided NiMo catalyst supported on pillared bentonite Al and Ti under hydrodeoxygenation reaction of guaiacol

International Journal of Renewable Energy Development
Bio-crude oil is known to be sustainable, eco-environmentally, and an alternative energy source produced by biomass pyrolysis. However, its quality remains relatively low due to a higher oxygen concentration compared to liquid fuels from fossils ...

Dual-Promoted Trimetallic CoMo-Ni/Al₂O₃-K₂O Catalysts: Impact of K₂O Doping on Guaiacol Hydrodeoxygenation Selectivity

Inorganics
The influence of potassium oxide (K2O) doping on the hydrodeoxygenation (HDO) performance of trimetallic CoMo–Ni/Al2O3 catalysts was systematically investigated using guaiacol as a lignin-derived model compound.

Formation of guaiacol from vanillin by Alicyclobacillus acidoterrestris in apple juice: a model study

, 2005
In this study, the formation of guaiacol from vanillin by Alicyclobacillus acidoterrestris in apple juice was investigated. Apple juices spiked with 10 and 100 mg/L of vanillin were inoculated with 1 x 10(3) CFU/mL and 1 x 10(5) CFU/mL spores of A ...
