Enhancing performance of Ni/La 2 O 3 catalyst by Sr-modification for steam reforming of toluene as model compound of biomass tar
Steam reforming of biomass tar with toluene as the model compound was studied using Sr-doped Ni/La 2 O 3 catalysts prepared using two methods, i.e. co-impregnation of Sr and Ni on La 2 O 3 support (Ni–Sr/La 2 O 3 catalyst) and sequential impregnation of Sr on Ni/La 2 O 3 catalyst (SNL catalyst), whi...

catalyst at the same calcination temperature due to the presence of Sr, which helps in water adsorption at low steam/carbon (S/C) ratio. Moreover, the catalytic performance for catalysts calcined at various temperatures decreases following this trend: 500 °C > 700 °C > 900 °C due to lower BET surface area and lower surface active metal available for reaction. In addition, it is also observed that the Sr/Ni/La
