What is Low temperature toluene and phenol abatement as tar model molecules over Ni-based catalysts: Influence of the support and the synthesis method about?

Ni addition over two ceria-based mixed oxides (Ce0.63Zr0.33Sm0.04O2− δ, and Ce2Y2O7) has been carried out by sol-gel (Ni-CZS and Ni-CY) and wet impregnation (Ni/CZS and Ni/CY) methods. The four catalysts were characterized by BET, XRD, TGA, XPS, H2-TPR and H2-chemisorption. Partial insertion of Ni2+ ions into both mixed oxide’s structure was found in the corresponding sol-gel catalysts. Their catalytic activity was evaluated in tar reforming, with toluene and phenol as model molecules, under isothermal condition at 400 and 550 °C for 6 h, using a typical ex-biomass syngas composition in order to mimic the real conditions of a gasification process. Among the four materials, Ni/CY was the best catalyst in terms of average tar conversion, whereas the best catalytic stability was obtained for Ni-CZS, owing to inserted Ni2+ species. This study demonstrates that Ni/CY can be a promising system for tar abatement at relatively low temperature through catalytic hot gas cleaning of a raw syngas generated by biomass gasification.
