摘　　要：采用等体积浸渍法制备了一系列不同Ni和Fe添加量的Ni-Fe/BaTiO3/γ-Al2O3双金属催化剂,并在固定床反应装置上考察了在873～1 073 K温度范围内催化剂对CO2和CH4重整反应的催化活性。实验结果表明:Ni、Fe负载质量分数均为5.0%的Ni-Fe/BaTiO3/γ-Al2O3催化剂活性最好。通过TPR、TPD和TPO表征并与单金属催化剂Ni/BaTiO3/γ-Al2O3相比,Ni-Fe/BaTiO3/γ-Al2O3催化剂具有更高的催化活性、脱附和抗积炭性能。A series of Ni-Fe/BaTiO3/γ-Al2O3 double metal catalysts with different amount of Ni and Fe are prepared using volumetric impregnation method.The catalytic activity of the obtained double metal catalysts for the CO2 and CH4 reforming reaction is investigated around 873-1 073 K temperature range in the fixed bed reaction device.The results show that the best catalyst activity can be achieved when the load of Ni and Fe is 5%.Compared with the single metal catalyst Ni/BaTiO3/γ-Al2O3,the double metal catalysts Ni-Fe/BaTiO3/γ-Al2O3 show higher catalytic activity,deportation and anticarbon deposition performance according to the results of TPR,TPD and TPO.
