Abstract
PROCEDIMIENTO PARA LIMPIAR UN SINTERIZADO USADO PARA FILTRAR UNA SUSPENSION CATALIZADORA METALICA. LA PRESENTE INVENCION SE REFIERE A UN PROCEDIMIENTO PARA LIMPIAR UN SINTERIZADO USADO PARA FILTRAR UNA SUSPENSION CATALIZADORA METALICA. COMO SE ENSEÑA POR LA INVENCION, EL SINTERIZADO SE TRATA CON UNA SOLUCION ACUOSA DE PEROXIDO DE HIDROGENO PARA EL DESPLAZAMIENTO DEL CATALIZADOR METALICO DEJADO EN LOS POROS DEL SINTERIZADO CON LA AYUDA DEL GAS PRODUCIDO POR LA DESCOMPOSICION DEL PEROXIDO DE HIDROGENO, CAUSADA POR EL CATALIZADOR METALICO, HASTA QUE CESA LA FORMACION DE GAS, INDICANDO QUE NO HAN QUEDADO CANTIDADES SIGNIFICATIVAS DE CATALIZADORES METALICOS EN EL SINTERIZADO.
