Abstract

PROCEDIMIENTO DE PREPARACION DE UN CATALIZADOR DE PLATA SOBRE UN SOPORTE. SE PONE EN CONTACTO UN VEHICULO POROSO INERTE CON UN LIQUIDO VOLATIL DE MODO QUE SE HUMEDEZCA DICHO VEHICULO, REVISTIENDO EL VEHICULO HUMEDO CON UNA SOLUCION AMONIACAL DE UNA SAL DE PLATA QUE PUEDE DEPOSITAR DE 2 A 8 POR CIENTO DE PLATA BASADO EN EL PESO DEL SOPORTE GRANULAR QUE DEBE TENER UN TAMAÑO DE PARTICULA DE 0,2 A 2,5 MM. LA SOLUCION DE LA SAL DE PLATA CONTIENE UN ACIDO GRASO QUE TIENE DE 12 A 22 ATOMOS DE CARBONO. EL REVESTIMIENTO SE DEBE SECAR SOBRE DICHO VEHICULO Y FINALMENTE SE DEBE CALCINAR DICHO VEHICULO REVESTIDO A UNA TEMPERATURA SUFICIENTE PARA OBTENER UN REVESTIMIENTO DE PLATA METALICA SOBRE EL. ES UTIL PARA LA FABRICACION DE FORMALDEHIDO A PARTIR DE METANOL Y GAS QUE CONTIENE OXIGENO.
