Experimental study on catalytic reforming characteristics of biomass tar model compounds with nickel-based magnesium slag catalyst
Ni/γ-Al2O3 and Ni/MS(magnesium slag)catalysts were prepared by the wet impregnation method,and furfural,toluene,naphthalene,and pyrene were selected as biomass tar analogues to study the catalytic reforming of four tar model compounds in a fixed-bed reactor using different nickel-based catalysts.Results show that when Ni/MS catalyst is used to catalyze the reforming of all tar analogues,the gas-phase carbon conversion rate and gas yield are significantly higher than those of Ni/γ-Al2O3 catalyst.When the amount of substance of water molecule and carbon atom is 1.5,the gas-phase carbon conversion rate of furfural reach the highest value of 86.54%.X-ray diffraction characterization(XRD)shows that the multiple solid solution(NiO-Fe2O3,NiO-MgO)on the Ni/MS catalyst form multiple active sites.
