Efficient hydro-deoxygenation of lignin derived phenolic compounds over bifunctional catalysts with optimized acid/metal interactions

Abstract

A stable bifunctional catalyst for hydro-deoxygenation of lignin derived phenolic compounds was obtained through simple selective deposition of Pt on alumina in a commonly used Al2O3-ZSM-5 nanocomposite, and the catalyst retained its complete deoxygenation capacity for more than 500 h.

Tandem Hydrogenolysis–Hydrogenation of Lignin‐Derived Oxygenates over Integrated Dual Catalysts with Optimized Interoperations

“…Overall, a 45 wt % of total carbon yield was obtained. Recently, Pt‐Al 2 O 3 /HZSM‐5 given a 77.27 % conversion with 53.63 % hydrocarbon selectivity in HDO of eugenol and exhibited activity in real bio‐oil . A two‐stage catalytic reactor was performed using Ru/C‐Pt/ZrP for HDO of bio‐oil, producing totally 30 wt % carbon yield .…”

“…Similarly, Pd/ m ‐MoO 3 ‐P 2 O 5 /SiO 2 was devoted to the HDO of water‐insoluble bio‐oils . Recently, Ju et al . used Pt‐alumina/zeolite with optimized acid/metal interaction, which can catalyze the HDO of bio‐oxygenates into hydrocarbons.…”

Recent Catalytic Approaches for the Production of Cycloalkane Intermediates from Lignin‐Based Aromatic Compounds: A Review

“…At 300 °C and 40 bar H 2 , the catalyst showed 38 % of cycloalkanes (from eugenol) including propylcyclohexane, 1‐methyl‐3‐propylcyclohexane, and other cyclo(hexane/pentane) derivatives. In addition, the catalyst is tested for the long run trial (500 h) and no changes in hydrodeoxygenation degree and stability/activity of catalyst was observed [96] …”
