Abstract : A study was made of the catalytic decomposition of bromotrifluoromethane, CBrF3, in air using a bench-scale reactor which simulates the CO/H2 catalytic burner of nuclear submarines. There was no indication of thermal decomposition of CBrF3 in presence of stainless steel at temperatures up 700F. In contact with Hopcalite catalyst under conditions of the shipboard CO/H2 burner, there was no detectable decomposition of CBrF3 at 600F and 100 ppm influent concentration. The extent of decomposition of CBrF3 appeared to be 3% or less under the most severe conditions studied. The presence of CBrF3 in the air did not interfere with the oxidation of carbon monoxide by the catalytic burner. (Author)
