Title: Method of catalytically reducing no contained in gas
Inventor: BERUNAA BAISUBAIRAA
IPC: B01J23/84
Filed: 1987-12-07
Abstract: A process of catalytically reducing NO contained in a gas which contains SO2. The NO is reduced with NH3, which is admixed to the gas which contains SO2 and NO. The mixture is supplied to the catalyst at a rate of 0.2 to 20 standard liters per minute and per gram of catalyst and is reacted with the latter in a fluidized bed at a temperature between 185 DEG  and 500 DEG  C. and under normal pressure. The catalyst has a particle size between 0.1 and 3 mm and is composed of an acid support and an active component, which consists of V2O5, MnO2, CuO, Fe2O3, NiO and/or Y2O3 and has been applied to the support in a quantity of 0.5 to 20% by weight. It is proposed that part of the catalyst is removed from the fluidized bed and is regenerated and returned to the fluidized bed.
