Abstract

Ordinary pulse reaction technique has been improved without the loss of the merits of pulse technique. A rectangular pulse (the width of which is more than 20 sec) was produced by using a rectangular pulse reaction apparatus developed in the present work. This technique has been applied to the NO-NH3 reaction on vanadium oxide catalysts with various oxidation states. In order to investigate the NH3 oxidation sites, the NO reduction sites and the mechanism of NO-NH3 reaction on vanadium oxide catalysts, results of NO-NH3 reaction and of the reaction of NH3 or NO over vanadium oxide catalysts with various oxidation states have been compared with the quantities of surface species such as V=0, V-OH, V-H and V∗+ examined by IR, ESR, and X-ray diffraction. The rectangular pulse technique was found to give useful information to the analysis of the NO-NH3 reaction under the dilute gas condition in the industrial NO removal process.
