Abstract

DESCRIBIMOS UN PROCEDIMIENTO PARA LA REDUCCION CATALICA DE NO, CONTENIDO EN UN GAS, CON NH3, DONDE SE ADICIONA AL GAS, QUE CONTIENE NO, NH3 EN RELACION MOLAR NO:NH3=1:1 Y SE LLEVAN A REACCIONES LA MEZCLA EN EL CATALIZADOR DE 185 A 500 C ASI COMO EN PRESION NORMAL. EL CATALIZADOR TIENE UN VEHICULO Y UN COMPONENTE CATALITICO Y EFICAZ. COMO VEHICULO SE UTILIZAN CRIBAS MOLECULARES O PURO -AL2O3, MIENTRAS COMO COMPONENETES ACTIVOS, CATALITICOS SE USA U2O5, MN2, CN2, FE2O3, NIO Y/O Y2O3. DESCRIBIMOS UN PROCEDIMIENTO PARA LA FABRICACION DEL CATALIZADOR.
