Continuous-flow hydroprocessing of long-chain fatty acids: reaction pathways and the impact of lignin-derived aromatics towards efficient deoxygenation

Key Points

• The study aims to explore oleic acid reaction pathways during continuous-flow hydroprocessing and the effects of lignin-derived aromatics.
• Long-term continuous-flow hydroprocessing of oleic acid
• Investigation of metal and acid sites in the reaction mechanism
• Co-feeding experiments with guaiacol to assess catalyst performance.
• Identified key reaction pathways for deoxygenation of oleic acid
• Guaiacol co-feeding enhanced catalyst activity despite certain limitations at high conversions.
