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 REACTORWHERE THE PROCESS INCLUDES: a) INTRODUCING THE SOLIDS IN A FLUIDIZED BED REACTOR, IN THE FORM OF GRANULES WITH A MAXIMUM GRAIN OF 2 mm, WHERE THEY ARE REDUCED WITH A REDUCING AGENT AT A TEMPERATURE BETWEEN 200 ° C AND 1000 ° C, WHERE THEY ARE AVERAGE DENSITY OF THE SUSPENSION OF THE FLUIDIZED BED IN THE REACTOR SET TO LESS THAN 1000 Kg / cm3; AND, b) INTRODUCE A FIRST GAS OR MIXTURE OF GASES FROM BELOW THROUGH A PIPE THAT FEEDS GAS IN A MIXING CHAMBER OF THE REACTOR, WHERE THE PIPE IS SURROUNDED BY A STATIONARY ANNULATE FLUIDIZED BED WHICH IS INTRODUCED BY THE GAS FLUIDIZED FLUIDIZER AND THE GAS SPEEDS OF THE FIRST GAS OR MIXTURE OF GASES AND THE FLUIDIZING GAS FOR THE BED ARE ADJUSTED SO THAT THE NUMBERS OF FROUDE OF PARTICLES IN THE PIPE ARE BETWEEN 1 AND 100, IN THE BED BETWEEN 0.02 AND 2, AND IN THE MIXING CHAMBER BETWEEN 0.3 AND 30. AS STARTING MATERIAL TO BE REDUCED, COPPER (I) OXIDE IS USED. THE REDUCTION AGENT IS GAS CONTAINING 80% TO 99.9% HYDROGEN AND BETWEEN 0 AND 20% NITROGEN. THE SOLIDS ARE DRYED BEFORE BEING LOADED IN THE REACTOR. AFTER REPROCESSING BY SEPARATION OF SOLIDS, SEPARATION BY COOLING AND WATER, AT LEAST PART OF THE WASTE GAS FROM THE REACTOR IS HEATED AND CIRCULATED TO THE REACTOR
