Abstract

PROCEDIMIENTO PARA LA PREPARACION DE CATALIZADORES BASADO EN OXIDOS DE HIERRO Y MOLIODENO. CONSISTE EN PONER EN CONTACTO UNA SOLUCION ACUOSA DE UNA SAL FERRICA SOLUBLE CON OTRA DE MOLIBDATO SODICO CON UN PH COMPRENDIDO ENTRE 5,0 Y 5,5 Y UN CONTENIDO EN MOLIBDENO DE 32 A 33 G/L. EL PRECIPITADO OBTENIDO, SE LAVA CON AGUA DESIONIZADA HASTA QUE EL CONTENIDO DE SODIO PRECIPITADO SEA IGUAL O INFERIOR A 150 PPM, A CONTINUACION SE TRATA EL PRECIPITADO LAVADO POR METODOS CONOCIDOS PARA OBTENER EL CATALIZADOR. LA RELACION MOLAR DEL MOLIBDENO COMO NOO RESPECTO AL HIERRO COMO FE O E ES MAYOR DE 2:1. LA SOLUCION DE MOLIBDATO SODICO SE OBTIENE POR REACCION DEL HIDROXIDO SODICO ACUOSO CON LOS CATALIZADORES AGOTADOS Y CON UN ACIDO MINERAL TAL COMO EL ACIDO CLORHIDRICO, EL NITRICO O EL SULFURICO.
