Characteristics of prototype mist singlet-oxygen generator for COIL

A mist singlet oxygen generator is possible to improve the HO2 utilization at the one pass reaction between basic hydrogen peroxide (BHP) and chlorine. In this investigation, BHP was atomized to small droplets by the gas flow. Chlorine, which is required for stoichiometric reaction with HO2 in the BHP, was used for atomization of BHP in order to reduce the buffer flow rate for atomization. We obtained the results that the conversion efficiency from chlorine to singlet oxygen (Ux Y) was 9.7% with purely chlorine atomization and 16% with x0.93 dilution ratio of nitrogen buffer at 18.7 mmol/s input chlorine flow and 5.8 ml/s BHP flow rate in a free space reaction chamber.
