Abstract

METODO DE PREPARACION DE SOPORTES DE CATALIZADORES DE ALUMINA. COMPRENDE LA IMPREGNACION DE UN SUSTRATO A BASE DE ALUMINA CON UNA DISOLUCION ACUOSA DE UN SILICATO AMONICO CUATERNARIO DE ALQUILO INFERIOR, DE MODO QUE LA CANTIDAD DE SILICE INTRODUCIDA EN EL SUSTRATO ESTA COMPRENDIDA ENTRE 0,1 Y 25% RESPECTO AL PESO DE SOPORTE; ADICION DE UN PRECURSOR DE OXIDO DE TIERRA RARA, DE ALCALINOTERREO O DE ZIRCONIO, ANTES, A LA VEZ O DESPUES DE LA ADICION DEL SILICATO DE AMONIO CUATERNARIO; SECADO DEL SUSTRATO IMPREGNADO, A UNA TEMPERATURA COMPRENDIDA ENTRE 80JC Y 500JC; Y CALCINACION DEL MISMO A UNA TEMPERATURA COMPRENDIDA ENTRE 500JC Y 1.000º DURANTE 1 A 24 HORAS. ESTOS SOPORTES TIENEN APLICACIONES PARA LA FABRICACION DE CATALIZADORES EMPLEADOS EN EL TRATAMIENTO DE GASES DE MOTORES DE COMBUSTION INTERNA Y NUMEROSAS REACCIONES ORGANICAS.
