In the O1 ClO2 generation process chloric acid is catalytically reduce
d in the presence of perchloric acid to produce a mixture of oxygen, c
hlorine dioxide, and water vapor. The purity of the chlorine dioxide g
as is 99.8% above the detection limits of the industry standard analyt
ical method. The generator can come to full production rate in less th
an five minutes. Potential applications include high consistency delig
nification and recycled fibre mills.
