Abstract

PROCEDIMIENTO PARA LA PREPARACION DE CATALIZADORES DEL TIPO DE ENVOLTURA, RESISTENTES AL DESGASTE Y ESTABLES FRENTE A LOS CAMBIOS DE TEMPERATURA. COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, UNA CARGA A GRANEL DE SOPORTE SE MEZCLA POR ACCION MECANICA EN UN MOVIMIENTO DE MEZCLADO Y SIMULTANEAMENTE SE LA DESCOHESIONA POR INSUFLACION, DESDE ABAJO, DE UNA CORRIENTE DE GAS FLUIDIZANTE, AL OBJETO DE REFORZAR EL MEZCLADO; SEGUNDA, SOBRE DICHA CARGA A GRANEL SE APORTA, EN CONTRACORRIENTE CON RELACION AL GAS, UNA SUSPENSION DE UN MATERIAL CATALITICAMENTE ACTIVO, QUE CONTIENE UN AGLUTINANTE Y EVENTUALMENTE UN FORMADOR DE POROS, EN UNA CANTIDAD CRECIENTE AL CRECER EL ESPESOR DE LA ENVOLTURA; Y POR ULTIMO, EL MATERIAL BRUTO SE SECA Y ATEMPERA EN EL GAS QUE SIGUE CIRCULANDO.
