抄録

The resistance to the effects of SO3 on the activity of the catalyst prepared from a mild steel plate was improved by addition of a vanadium compound and by calcination at temperature above 600°C. The reaction kinetics of NO reduction with NH3 on the modified catalyst can also be expressed by the equation, <br>-1/KNH<sub>3</sub>(PNH<sub>3</sub>in-PNOin)•ln(1-x)PNH<sub>3</sub>in/PNH<sub>3</sub>in-xPNOin-ln(1-x)=k'RPT√KO<sub>2</sub>inPO<sub>2</sub>in/1+KH<sub>2O</sub>PH<sub>2O</sub>in+√KO<sub>2</sub>PO<sub>2</sub>in•A/F<br>which was originally proposed for the reaction kinetics on the unmodified catalyst.1)<br>The durability of a modified catalyst of the honeycomb form was verified by the results of the catalyst life tests done with the flue gas from a heavy oil fired boiler.
