Abstract

In order to reveal the optimum Co loading, the selective catalytic reduction of NO with C3H6 over Co/Al2O3 catalyst was studied in a systematic fashion by varying the amount of cobalt oxide. It was found that upon loading a small amount of cobalt oxide (namely 0.5 wt% on a Co metal basis), the combination between Co(II) acetate salt and a high-purity alumina provided an active catalyst in the presence of excess oxygen and water. TPR measurement showed the presence of Co species other than CoAl2O4 spinel in the most excellent performance catalyst, from which the active sites should be produced.
