Abstract

UN METODO DE AMOXIDACION EN UN REACTOR DE LECHO FLUIDIZADO, EN EL CUAL, CUANDO UN MATERIAL DE PARTIDA QUE VA A SER AMOXIDADO SE AMOXIDA MEDIANTE UNA REACCION EN LECHO FLUIDIZADO CATALITICA EN FASE DE VAPOR, LA REACCION SE LLEVA A CABO EN UN REACTOR DE LECHO FLUIDIZADO AL CUAL SE INTRODUCE GAS QUE CONTIENE OXIGENO A TRAVES DE UNAS ABERTURAS DE ENTRADA SITUADAS EN EL FONDO DEL MISMO Y UN MATERIAL DE PARTIDA QUE VA A SER AMOXIDADO SE INTRODUCE A TRAVES DE UNAS ABERTURAS DE ENTRADA SITUADAS POR ENCIMA DE LAS ABERTURAS DE ENTRADA PARA EL GAS QUE CONTIENE OXIGENO, SIENDO LA DISTANCIA ENTRE LAS ABERTURAS DE ENTRADA PARA EL GAS QUE CONTIENE OXIGENO Y LAS DEL MATERIAL DE PARTIDA ENTRE 30 Y 250 % DE LA ALTURA DE UN MATERIAL SOLIDO FLUIDIZADO EN UN ESTADO ESTATICO, DE MANERA QUE SE FORMA UN LECHO FLUIDIZADO TAL QUE LA DENSIDAD DEL MATERIAL SOLIDO FLUIDIZADO EN LAS ABERTURAS DE ENTRADA DEL MATERIAL QUE VA A SER AMOXIDADO ESTA EN EL INTERVALO DE ENTRE 50 Y 300 KG/M SUP,3} Y LA VELOCIDAD DEL GAS ES 1 M/SO INFERIOR. MEDIANTE ESTE METODO, LA EFICACIA DEL CONTACTO ENTRE LAS PARTICULAS DE CATALIZADOR Y UN MATERIAL DE PARTIDA Y EL RESULTADO DE LA REACCION (EL RENDIMIENTO DE UN PRODUCTO DESEADO) SE VEN MEJORADOS. UN EJEMPLO ESPECIFICO DE LA PRESENTE INVENCION ES UN METODO PARA LA AMOXIDACION DEL METANOL, EN EL CUAL, CUANDO LA AMOXIDACION CATALITICA EN FASE DE VAPOR DEL METANOL SE LLEVA A CABO EN UN REACTOR DE LECHO FLUIDIZADO PARA OBTENER ACIDO CIANHIDRICO, LA REACCION SE LLEVA A CABO UTILIZANDO, COMO CATALIZADOR, UN OXIDO METALICO QUE CONTIENE [I] AL MENOS UN ELEMENTO SELECCIONADO ENTRE EL GRUPO QUE CONSISTE EN HIERRO, ANTIMONIO, FOSFORO Y COBRE Y [II] AL MENOS UN ELEMENTO SELECCIONADO ENTRE EL GRUPO QUE CONSISTE EN VANADIO, MANGANESO, MOLIBDENO, TUNGSTENO Y BISMUTO, INTRODUCIENDO EN EL LECHO DEL CATALIZADOR UN GAS QUE CONTIENE OXIGENO A TRAVES DE LAS ABERTURAS DE ENTRADA SITUADAS EN LA PARTE INFERIOR DEL REACTOR Y METANOL Y AMONIACO COMO GAS QUE CONTIENE VAPOR DE AGUA A TRAVES DE LAS ABERTURAS SITUADAS POR ENCIMA DE LAS ABERTURAS DE ENTRADA PARA EL GAS QUE CONTIENE OXIGENO O INTRODUCIENDO TODA O PARTE DEL VAPOR DE AGUA EN EL LECHO DEL CATALIZADOR A TRAVES DE LAS ABERTURAS DE ENTRADAS SITUADAS POR DEBAJO DE LAS ABERTURAS DE ENTRADA DEL METANOL Y DEL AMONIACO, CON UNA RELACION MOLAR ENTRE VAPOR DE AGUA Y METANOL AJUSTADA ENTRE 0,1 Y 3. MEDIANTE ESTE METODO, LA REACCION SE PUEDE LLEVAR A CABO EFICAZMENTE INCLUSO EN TALES CONDICIONES DE REACCION EN QUE LA CANTIDAD DE OXIGENO O AMONIACO EN RELACION A LA DEL METANOL CONTENIDA EN UN GAS INTRODUCIDO ES PEQUEÑA Y EL PRODUCTO DESEADO, ES DECIR, EL ACIDO CIANHIDRICO, SE PUEDE OBTENER ASI CON UN ALTO RENDIMIENTO Y SIENDO TAMBIEN ESTABLE CON EL TIEMPO.
