Abstract

UN METODO DE PREPARAR UN CATALIZADOR PARTICULARMENTE UTIL EN LA REACCION DE ETILENO, OXIGENO Y ACIDO ACETICO EN LA FASE VAPOR PARA FORMAR ACETATO VINIL COMPRENDE IMPREGNAR UN SOPORTE POROSO CON SALES DE PALADIO Y ORO SOLUBLES EN AGUA, QUE FIJAN EL PALADIO Y EL ORO EN EL SOPORTE COMO COMPONENTES INSOLUBLES EN AGUA POR CONTACTAR EL SOPORTE IMPREGNADO DE SAL CON UNA SOLUCION REACTIVA EN DOS ETAPAS DE FIJACION SEPARADAS EN DONDE EL SOPORTE TRATADO ES SECADO Y PERMITIDO A PERMANECER ANTES DEL TRATAMIENTO EN LA SEGUNDA ETAPA PARA PRECIPITAR LOS COMPONENTES INSOLUBLES EN EL SOPORTE Y REDUCIR LOS COMPONENTES INSOLUBLES PARA LIBERAR EL PALADIO Y EL ORO. EL CATALIZADOR PREPARADO EN LA FORMA HA SIDO MOSTRADO PARA PROVEER MEJORAS CON RESPECTO A LA SELECTIVIDAD REDUCIDA AL CO2 DURANTE LA REACCION DE FORMACION DE ACETATO VINIL.
