Abstract

In the present study, core-shell Al₂O₃ was synthesized by hydrothermal method and employed as support for the preparation of Ni/Al₂O₃ catalysts via an impregnation method. The toluene thermal-reforming was investigated in a fluidized bed reactor using these core-shell Ni/Al₂O₃ catalysts. The catalysts were characterized with TEM, BET, XRD and H₂-TPR techniques. Compared with the catalysts supported on commercial Al₂O₃, core-shell catalysts exhibited higher specific surface areas, smaller Ni particle sizes and higher catalytic activities. The core-shell catalysts showed high stability during 48h thermal-reforming.
