Abstract
EL GAS A DESULFURAR SE PONE EN CONTACTO CON UN CATALIZADOR CONSTITUIDO POR UNA FASE CATALITICA ASOCIADA A UN SOPORTE DE CARBURO DE SILICIO PARA REALIZAR LA REACCION DE FORMACION DE AZUFRE ENTRE H{SUB,2}S Y SO{SUB,2} Y EVENTUALMENTE LA REACCION DE HIDROLISIS DE LOS COMPUESTOS COS Y CS{SUB,2} Y H{SUB,2}S, A TEMPERATURAS QUE, SEGUN LA IMPLEMENTACION ELEGIDA, PUEDEN SER SUPERIORES O INFERIORES AL PUNTO DE ROCIO DEL AZUFRE FORMADO EN LOS GASES DE REACCION. APLICACION EN LA RECUPERACION, EN FORMA DE AZUFRE, DE LOS COMPUESTOS H{SUB,2}S Y SO{SUB,2} CONTENIDOS EN GASES DE VARIOS ORIGENES, PARTICULARMENTE GAS DEL PROCEDIMIENTO CLAUS, AI COMO EN LA HIDROLISIS EN H{SUB,2}S DE LOS COMPUESTOS COS Y CS{SUB,2} EVENTUALMENTE CONTENIDOS EN ESTOS GASES.
