Metal oxide-catalyzed hydrothermal liquefaction of Malaysian oil palm biomass to bio-oil under supercritical condition
Effect of metal oxide catalysts such as CaO, MgO, MnO, ZnO, NiO, SnO, CeO2, Al2O3 and La2O3 on supercritical hydrothermal liquefaction of empty fruit bunch (EFB) derived from oil palm residues to bio-oil were studied in terms of product yields and characteristics. EFB, water and 1.0 wt metal oxide w...
