Abstract

DONDE EL PROCESO COMPRENDE: a) INTRODUCIR LOS SOLIDOS EN UN REACTOR DE LECHO FLUIDIZADO, EN FORMA DE GRANULOS CON UN GRANO MAXIMO DE 2 mm, DONDE SON REDUCIDOS CON UN AGENTE DE REDUCCION A UNA TEMPERATURA ENTRE 200°C Y 1000°C, SIENDO LA DENSIDAD MEDIA DE LA SUSPENSION DEL LECHO FLUIDIZADO EN EL REACTOR AJUSTADA A MENOS DE 1000 Kg/cm3; Y, b) INTRODUCIR UN PRIMER GAS O MEZCLA DE GASES DESDE ABAJO A TRAVES DE UNA TUBERIA QUE ALIMENTA GAS EN UNA CAMARA DE MEZCLADO DEL REACTOR, DONDE LA TUBERIA ES RODEADA POR UN LECHO FLUIDIZADO ANULAR ESTACIONARIO EL CUAL ES FLUIDIZADO POR LA INTRODUCCION DE GAS FLUIDIZANTE Y LAS VELOCIDADES DE GAS DEL PRIMER GAS O MEZCLA DE GASES Y EL GAS FLUIDIZANTE PARA EL LECHO SON AJUSTADAS DE MODO QUE LOS NUMEROS DE FROUDE DE PARTICULAS EN LA TUBERIA ESTAN ENTRE 1 Y 100, EN EL LECHO ENTRE 0,02 Y 2, Y EN LA CAMARA DE MEZCLADO ENTRE 0,3 Y 30. COMO MATERIAL DE PARTIDA A SER REDUCIDO SE USA OXIDO DE COBRE (I). EL AGENTE DE REDUCCION ES GAS QUE CONTIENE DE 80% A 99,9% DE HIDROGENO Y ENTRE 0 Y 20% DE NITROGENO. LOS SOLIDOS SON SECADOS ANTES DE SER CARGADOS EN EL REACTOR. LUEGO DE REPROCESAR POR SEPARACION DE SOLIDOS, SEPARACION POR ENFRIAMIENTO Y AGUA, AL MENOS PARTE DEL GAS DE DESECHO DEL REACTOR ES CALENTADO Y CIRCULADO AL REACTOR
