Abstract

PROCEDIMIENTO PARA LA OBTENCION DE CATALIZADORES SOPORTADOS CONTENIENDO PLATA Y EN CASO DADO PROMOTORES. SE IMPREGNA UN SOPORTE CON ACIDO LACTICO CONTENIENDO PLATA CON UN CONTENIDO DE ACIDO LACTICO OPTIMAMENTE ACTIVO, COMPUESTOS ORGANICOS SOLUBLES DE FACIL DESCOMPOSICION Y NO REDUCTORES Y EN CASO DADO IONES DE METAL PROMOTOR. DESPUES SE SECA ENTRE 50 Y 120 C Y SE DESCOMPONEN LOS COMPONENTES ORGANICOS EN DOS FASES DE CALENTAMIENTO DE 140-220 Y 400-500 C, RESPECTIVAMENTE. SECADO Y DESCOMPOSICION SE REALIZAN EN ATMOSFERA LIBRE DE OXIGENO. EL PRODUCTO INTERMEDIO OBTENIDO ANTERIORMENTE SE ACTIVA POR CALENTAMIENTO ENTRE 130 Y 300 C EN ATMOSFERA CONTENIENDO OXIGENO DE UN REACTOR.
