Co-Mo/Al_2O_3-MgO耐硫变换催化剂的表征研究

Study on the Characterization of Co-Mo/Al_2O_3-MgO Sulfur-tolerant Shift Catalyst

采用常压微反、程序升温还原(TPR)、程序升温硫化(TPS)及原位红外(IR)技术,对Co-Mo/Al2O3-MgO催化剂表征研究发现:Co-Mo/Al2O3-MgO催化剂中活性组分Co、Mo,既存在着Co、Mo中心,也存在由Co、Mo相互作用产生的中心,其催化性能是由Co、Mo中心和Co、Mo相互作用产生的中心共同作用的结果,与Co-Mo/Al2O3催化剂是不同的,其中的MgO加强了活性组分Co、Mo的稳定性,进一步促进了Co、Mo的相互作用。

The characterization of the Co-Mo/Al2O3-MgO catalyst was studied in this paper,which measured by atmospheric micro-reaction,temperature-programmed reduction(TPR),temperature-programmed sulfiding(TPS),insitu infrared ray(IR) technique.It releases that the active components Co and Mo in the Co-Mo/Al2O3-MgO catalyst as the same as the active components in the Co-Mo/Al2O3 catalyst have not only the centers of Co and Mo but also the center produced by the interaction between Co and Mo,and the performance of the ...
