Tóm tắt

The effect of Ni:Al molar ratio on structural properties of nickel aluminates spinel and its catalytic performance in selective catalytic reduction of NO with C3H3 was investigated. Characterization of this material was carried out by a variety of techniques such as XRD, Hr TPR, SEM and N2 adsorption-desorption isotherms. Catalytic activity of nickel aluminates spinel in selective catalytic reduction of NO by propane (C3H3-SCR of NO) was studied in a micro-reactor system at 1 atm. A relationship between the structure of the spinel and its catalytic function for C3H3-SCR-NO was also clarified in detail in the study.
