Abstract

EL PROCEDIMIENTO OXIDANTE - NH3 FUNCIONA CON UN CATALIZADOR (6, 32) QUE CONTIENE AL LADO DE BIOXIDO DE TITANIO (TIO2) PREFERIBLEMENTE UNO O VARIOS DE OXIDO METALICOS DE TRANSICION, OXIDO DE CROMO (CR2 O3) OXIDO DE MANGANESO (MN O2) Y OSIDO DE COBRE (CU O). EL CATALIZADOR (6, 32) OXIDA EL AMONIACO (NH3) A PRODUCTOS DE CADENCIA NO PELIGROSOS MISMO A NITROGENO (N2) Y AGUA (H2O). SE DESCRIBEN DISPOSITIVOS PARA LA EJECUCION DEL PROCEDIMIENTO TANTO PARA GASES PERDIDOS (A) CALIENTES COMO FRIOS, LO MISMO COMO METODOS PARA LA FABRICACION DEL CATALIZADOR (6, 32)
