Abstract

UN SORBENTE DE ALUMINA CAPAZ DE ABSORBER NOX Y SOX DE LOS GASES DE DESECHO Y QUE SE REGENERA SI SE CALIENTA A 650 (GRADOS) C SE FORMA INCORPORANDO UN AGENTE ESTABILIZADOR DE LA ALUMINA EN EL SORBENTE. UNO DE LOS METODOS PREFERENTES CONSISTE EN AÑADIR EL ESTABILIZADOR CUANDO SE PRECIPITA LA ALUMINA. CON EL POLVO PRECIPITADO SE FORMA DESPUES UNA SUSPENSION QUE SE MUELE Y SE SECA POR PULVERIZACION PARA FORMAR LAS PARTICULAS DE ALUMINA ESFEROIDALES ESTABILIZADAS QUE TIENEN UN TAMAÑO DE PARTICULA INFERIOR A 500 MICRAS. ESTAS PARTICULAS SE IMPREGNAN CON UN METAL ALCALINO O CON UN METAL ALCALINO-TERREO PARA FORMAR EL SORBENTE ESTABILIZADO. COMO ESTABILIZADORES DE LA ALUMINA SE PUEDEN UTILIZAR UNO O MAS DE LOS SIGUIENTES: SILICE, LANTANA, OTRAS TIERRAS RARAS, TITANIA, ZIRCONIA Y TIERRAS ALCALINAS.
