Abstract
PURPOSE: A new denitrizing catalyst consists of TiO2 carrying as active ingredient a specific proportions of WO3 and V2O5 respectively and has a highly efficient function when used in NH3 reduction process for contact-reducing removal of NOx without being adversely affected by SOx or dust.
CONSTITUTION: A denitrizing catalyst is represented by the formula in which TiO2 is present in the form of anatase type. In the catalyst, the optimum ratio of WO3/ V2O5 is 2 to 5 and WO3+V2O5/TiO2 ratio of 0.03 to 0.12 is preferable. The catalyst is prepared as follows. V2O5 is dissoved in oxalic acid to form weak acidic solution of vanadyl oxalate, which is impregnated into TiO2 to be carried by, and then dried. The TiO2 carrier so impregnated and dried is next impregnated with para tungustate ammonium solution in aliphtic amine then dried and fired. The resultant catalyst has an excellent dinitration property and inhibits the oxydation reaction of SO2 to SO3.
