Article Synopsis
- Graphene materials are valuable due to their extraordinary properties, but their production is challenging.
- This research explores a plasma-based technique that exfoliates and modifies graphite flakes using shock waves and chemical species at a liquid surface.
- The resulting process reduced the thickness of graphite by 20% and produced a unique structure with minimal defects, offering a promising new approach to creating functionalized graphenic materials.
Lignin is a potential renewable material for the production of bio-sourced aromatic chemicals. We present the first hydrotreatment of lignin pyrolysis vapors, before any condensation, using inexpensive and sustainable iron-silica (Fe/SiO2 ) and iron-activated carbon (Fe/AC) catalysts. Lignin pyrolysis was conducted in a tubular reactor and vapors were injected in a fixed bed of catalysts (673 K, 1 bar) with stacks to investigate the profile of coke deposit.
