 Steam reforming of toluene over nickel catalysts supported on coal gangue ashMin Lu, Zuhong Xiong, Kejing Fang, Xi Li, Jiqing Li and Tao Li Renewable Energy, 2020, vol. 160, issue C, 385-395 Abstract: The development of high performance and low-cost catalyst is very important to remove tar during biomass gasification. Solid waste coal gangue ash (CGA), which mainly contains SiO2, Al2O3, Fe2O3 and CaO, was selected as support for Ni-based catalyst. The prepared low-cost catalysts were characterized suitably by XRD, BET, TPR, SEM, TG and Raman techniques. Toluene was selected as typical biomass tar model compounds to test the catalyst performance and compared with traditional catalysts Ni/Al2O3 and Ni/SiO2. Ni/CGA-1d exhibited the highest catalytic performance with the toluene conversion and H2 yield accounting for 91.5% and 58.2% respectively, at 800 °C. It was showed that the performance of Ni/CGA-1d was higher than traditional catalysts Ni/Al2O3 and Ni/SiO2, and comparable with other polymetallic reforming catalysts. Due to the good resistance of carbon deposition, the Ni/CGA-1d catalyst also performed better catalytic activity stability. The ability should be attributing to the existence of some metal elements such as Fe, Mg, K, Ca et al. in coal gangue ash support.
