Abstract

The net formation of sulfur trioxide in the presence of an excess of carbon monoxide with respect to sulfur dioxide was studied under different reaction conditions in a single element of a commercial monolithic Pt, Rh converter. Conditions giving rise to self-oscillations were found to result in a complete oxidation of carbon monoxide and in only a 10% net conversion of sulfur dioxide.

振荡反应条件对整体式汽车催化转化器中三氧化硫生成的抑制作用
在商业单片Pt, Rh转炉的不同反应条件下,研究了在一氧化碳相对于二氧化硫过量的情况下,三氧化硫的净形成。发现引起自振荡的条件导致一氧化碳完全氧化,而二氧化硫的净转化率仅为10%。
