The removal of tar and CO2 represents a critical challenge in the production biomass gasification syngas, necessitating development advanced catalytic systems. In this study, plasma-enhanced reforming was employed to remove tar, with toluene selected as model compound for tar. Supported Nix-Fey/Al2O3 catalysts, varying Ni/Fe molar ratios (3:1, 2:1, 1:1, 1:2, 1:3), were synthesized dielectric barrier discharge (DBD) non-thermal plasma reactors. experiments conducted at 250 °C ambient pressure. effects various ratios, powers, concentrations on DBD plasma-catalytic synthesis gas analyzed. results indicate that CO H2 are primary gaseous products decomposition, selectivity these increasing power. Increasing power leads higher production. A CO2/C7H8 ratio 1.5 found effectively enhance performance system, leading highest conversion syngas selectivity. catalysts follows following order: Ni3-Fe1/Al2O3 > Ni2-Fe1/Al2O3 Ni1-Fe1/Al2O3 Ni1-Fe2/Al2O3 Ni1-Fe3/Al2O3. Notably, catalyst exhibits high adsorption capacity due its strong basicity, demonstrating significant potential both carbon resistance.
