Abstract

SE HACE MEZCLAR EL GAS QUE CONTIENE EL H2S CON UN GAS QUE CONTIENE OXIGENO LIBRE, EN CANTIDAD PARA OBTENER UNA RELACION MOLAR O2:H2S DE 0,5 A 3 Y PREFERENTEMENTE 0,5 A 1,5, Y SE PONE EN CONTACTO CON UN CATALIZADOR DE OXIDACION DEL H2S EN AZUFRE, EFECTUANDO DICHO CONTACTO CON TEMPERATURAS INFERIORES A 200 (GRADOS) C. EL CATALIZADOR CONSISTE EN UN SUSTRATO DE CARBON ACTIVO AL CUAL SE INCORPORA UNA FASE CATALITICA ELEGIDA ENTRE LOS COMPUESTOS OXIDO, SALES O SULFURO DE UNO O VARIOS METALES DE TRANSICION ENTRE V, MO, W, NI Y CO, REPRESENTANDO LA CANTIDAD DE LA FASE CATALITICA, MOSTRADA EN PESO DEL METAL DE TRANSICION, ENTRE 0,1% A 15% DEL PESO DEL CATALIZADOR CALCINADO.
