Tandem Hydrodeoxygenation Catalyst System for Hydrocarbons Production from Simulated Bio-oil: Effect of C–C Coupling Catalysts

Research in the sustainable conversion of biomass to fuels and chemicals is a necessity for reduction carbon footprint transport energy. Herein, we demonstrate an efficient tandem catalyst selectively convert (simulated) bio-oil hydrocarbons with enhanced C4+ fuel yield fixed bed reactor small pilot plant. The catalytic system multifunctional dual system; coupling catalysts (0.2 wt % X-TiO2(X: Ru, Pd, Au) at upper layer hydro-deoxygenation (Ru-MoFeP/Al2O3) bottom single reactor. upper-bed facilitated reaction C2–C4 light oxygenates significantly reduced gases (C1–C5) ca. 40% increased organic (C4+) phase 15%. analysis suggests that among screened upstream catalysts, 0.2 Ru/TiO2||Ru-MoFeP/Al2O3 recorded optimum activity. coupled (acetone) alkylated phenolic compounds sequentially hydro-deoxygenated higher hydrocarbons. This versatile approach has potential application emerging biorefinery concept.
