| Abstract: | The kinetics of the reduction of NO by NH3 in the presence of O2 in molten salts of 50mol% NH4HSO4 and 50mol% NaHS04 with a V2O5 as catalyst was investigated by chemical absorption method using a bubble column reactor at temperatures ranging 150 to 180°C. The rate of the reduction of NO could be expressed as first-order with respect to the concentration of NO. The first-order reaction rate constants with V2O5 and V2O5-NH4Br-TiO2-SiO2 as catalyst were determined. The Henry's law constants of NO in the molten salts were determined in the same range of temperature. |
