A study of a singlet-oxygen generator with a twisted aerosol flow

The results of a study of a singlet-oxygen generator (SOG) with a twisted aerosol flow are presented. The output parameters of the generator obtained in experiments exceed the corresponding characteristics reported earlier in the literature. The maximum chemical efficiency of the reactor amounts to ~70%. The flux density of the electron energy stored by the excited oxygen molecules in the reaction zone is above 1.5 kJ cm^-2 s^-1. The measured singlet-oxygen yield is ~60% at a pressure of 100 Torr. Adding a buffer gas (N₂) to chlorine ensures an increase in the outlet pressure up to 250 Torr without a decrease in the singlet-oxygen yield. The utilisation of chlorine under such conditions exceeds 95%. The SOG design with a twisted flow ensures atmospheric pressure of the waste solution at the reactor outlet, thus significantly simplifying the development of a system for liquid recycling.
