Abstract

SE PRESENTA UN METODO PARA PARAR Y PONER EN MARCHA UN REACTOR EQUIPADO CON UN CAMBIADOR DE CALOR, UN REGULADOR CATALITICO, UN FILTRO CATALITICO Y SIMILARES, Y QUE ES ADECUADO PARA EL USO EN UN PROCEDIMIENTO PARA LA PREPARACION DE ACRILAMIDA HACIENDO REACCIONAR ACRILONITRILO CON AGUA EN PRESENCIA DE UN CATALIZADOR A BASE DE COBRE METALICO USADO COMO LECHO SUSPENDIDO. DE ACUERDO CON ESTE METODO PUEDEN EVITARSE VARIOS FENOMENOS INDESEABLES QUE PUEDEN OCURRIR AL COMIENZO DE LA OPERACION DESCARGANDO EL CATALIZADOR HASTA QUE TODA LA CANTIDAD DE COBRE METALICO Y DE OXIDOS DE COBRE PRESENTE EN EL CATALIZADOR QUE QUEDA EN EL REACTOR NO SOBREPASE UN CIERTO NIVEL BASADO EN LA CANTIDAD DE CATALIZADOR DE COBRE METALICO USADO AL PRINCIPIO DE LA OPERACION, O DESCARGANDO EL CATALIZADOR HASTA QUE LA CANTIDAD DE OXIDOS DE COBRE NO SOBREPASE UN CIERTO NIVEL Y ESTABLECIENDO DESPUES UN AMBIENTE INERTE DENTRO DEL REACTOR.
