Abstract

SE EXPONE UN PROCEDIMIENTO PARA PRODUCIR AMINAS AROMATICAS POR HIDROGENACION CATALITICA DE LOS CORRESPONDIENTES COMPUESTOS NITRO AROMATICOS, EN LA FASE GASEOSA, SOBRE CATALIZADORES FIJOS QUE CONTIENEN UNO O VARIOS METALES DE LOS GRUPOS VIIIA,, IB, IIB, IVA, VA, VIA, IVB Y VB DE LA TABLA PERIODICA DE ELEMENTOS (MENDELEJEW) SOBRE UN SUBSTRATO METALICO, CON UNA SUPERFICIE BET DE MENOS DE 40 M 2 /G, A RELACIONES MOLARES ENTRE LOS GRUPOS HIDROGENO Y NITRO DE 3:1 A 30:1, Y A TEMPERATURAS EN EL LECHO CATALITICO DE 180 A 500 C. EL PROCEDIMIENTO SE CARACTERIZA PORQUE LA CARGA DEL COMPUESTO NITRO AROMATICO DEL CATALIZADOR SE AUMENTA DE FORMA CONTINUA O GRADUAL DE 0,01-0,5 A 0,7-5,0 KG/L X H, ALCANZANDOSE LA CARGA MAXIMA EN EL PLAZO DE 100 A 1.000 HORAS. ESTE PROCEDIMIENTO PUEDE DESARROLLARSE SIN PROBLEMAS A ESCALA INDUSTRIAL, Y ASEGURA UN ELEVADO RENDIMIENTO EN CUANTO A TIEMPO Y ESPACIO, JUNTO CON UNA MEJOR PRODUCTIVIDAD DE LOS CATALIZADORES UTILIZADOS.
