摘要

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%。

Suppression of sulfur trioxide formation in a monolithic catalytic converter for cars due to oscillating reaction conditions
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.
