摘要： 采用等体积浸渍将双金属活性组分负载到介孔分子筛SBA-16上, 通过热分解制备了负载型催化剂Ni-b-Mo2C/SBA-16. N2吸附-脱附、X射线粉末衍射和透射电镜等结果表明, 引入活性组分后, 样品依然保持原有的有序介孔结构, 活性组分高度分散于载体上, 没有团聚. 在CH4/CO2重整制合成气反应中, Ni-?-Mo2C/SBA-16催化剂具有较高的CH4和CO2转化率, 以及CO和H2选择性, 有明显的抗积炭作用.

Abstract: Mesoporous molecular sieve SBA-16 supported bimetallic carbide catalyst Ni-b-Mo2C/SBA-16 was prepared using the impregnation and thermal decomposition method. N2 adsorption-desorption isotherms, powder X-ray diffraction, and transmission electron microscopy measurements show that the active components were uniformly dispersed on the support, and the catalyst still remained ordered mesoporous structure of SBA-16. Catalytic performance measurements show that the catalyst exhibited higher conversion rate of CH4, CO2, and selectivity of CO, H2, and remarkable anti-coke effect.
