Abstract

SE PRESENTA UNA DISPERSION ESPESA Y LIBRE DE AGUA DE CATALIZADORES RANEY EN MEDIOS INCRUSTADORES ORGANICOS QUE SON FUNDIBLES. UNA DISPERSION PUEDE OBTENERSE SIGUIENDO LOS PASOS SIGUIENTES: MEZCLAR LOS LODOS DE CATALIZADORES RANEY CON MEDIOS INCRUSTADORES EN ATMOSFERA DE GAS INERTE Y EN UN MEZCLADOR A VACIO, DESHIDRATAR LA MEZCLA CALENTANDOLA A UNA TEMPERATURA POR DEBAJO DEL PUNTO DE FUSION DE LOS MEDIOS DE INCRUSTACION, EN VACIO Y CON AGITACION Y CALENTAR LA MEZCLA POR ENCIMA DEL PUNTO DE FUSION DE LOS MEDIOS INCRUSTADORES, EN VACIO Y CON AGITACION, PARA ELIMINAR EL CONTENIDO RESIDUAL DE AGUA EN LA MEZCLA. SEGUN LA DESHIDRATACION SE ELIMINA EL VACIO CON GAS INERTE Y EL PRODUCTO SE CONFORMA EN FORMA POCO SUPERFICIAL
