Abstract

LA INVENCION SE REFIERE A UN PROCESO PARA LA ELIMINACION DE HCN A PARTIR AL MENOS DE MEZCLAS QUE CONTIENEN HCN Y COMPUESTOS DE AZUFRE, EN PARTICULAR MEZCLAS DE GASES OBTENIDAS A PARTIR DE LA OXIDACION PARCIAL DE HIDROCARBUROS, MEDIANTE DESCOMPOSICION CATALITICA DEL HCN. LA INVENCION SE REFIERE TAMBIEN A UN CATALIZADOR PARA LA DESCOMPOSICION DEL HCN. LA INVENCION PROPONE QUE LA MEZCLA DE GAS SEA PUESTA EN CONTACTO CON UN CATALIZADOR QUE DESCOMPONE EL HCN MEDIANTE HIDROGENACION Y/O HIDROLISIS, AL MENOS DESCOMPONIENDOSE ALGO DE COS EN LA MEZCLA SOBRE EL CATALIZADOR MEDIANTE HIDROLISIS. CON PREFERENCIA EL CATALIZADOR UTILIZADO COMPRENDE OXIDO DE TITANIO Y/O OXIDO DE ZIRCONIO COMO MATERIAL SOPORTE Y OXIDO DE CROMO COMO COMPONENTE ACTIVO. ADICIONALMENTE EL CATALIZADOR ES REDUCIDO CON PREFERENCIA CUANDO HA SIDO ELABORADO O INMEDIATAMENTE ANTES DE SU USO, POR MEDIO DE H{SUB, 2} Y/O OTRO AGENTE DE REDUCCION GASEOSO A UNA TEMPERATURA POR ENCIMA DE LA TEMPERATURA EN QUE SE REALIZA LA REACCION DE DESCOMPOSICION CATALITICA.
