Abstract
Catalytic properties of γ-Al2O3 -supported complex vanadium and chromium oxides V2−x Cr x O5−δ (0 < × s 1.3), amorphous to X-rays, in the reduction of nitrogen oxides with ammonia were studied. Vanadium exists in these catalysts mostly in a pentavalent state and chromium exists as Cr3+ and Cr6+. As the content of chromium in the catalysts increases, the optimal temperature of the process decreases, and the degree of conversion of nitrogen oxides increases.
