Abstract
ESTA REFERIDO A UN PROCESO EN EL CUAL EL GAS DE SINTESIS, PREFERENTEMENTE GAS NATURAL REFORMADO, ES MEZCLADO CON GAS DE TOPE QUE SE FORMA EN LA REDUCCION DIRECTA DEL MATERIAL QUE CONTIENE EL OXIDO DE HIERRO CARACTERIZADO PORQUE EL GAS DE REDUCCION ES AJUSTADO PARA UNA RAZON DEFINIDA DE CO/CO2 ENTRE 1 Y 3, PREFERIBLEMENTE ENTRE 1,5 Y 2,0, POR EL AJUSTE DE LAS CARACTERISTICAS DE OPERACION PARA LA PRODUCCION DE GAS DE SINTESIS DE GAS NATURAL POR REFORMACION, POR LA VARIACION DE LA RAZON DE VAPOR/GAS NATURAL DURANTE LA ALIMENTACION DEL REFORMADOR, DONDE LA RAZON ES AJUSTADA DENTRO DEL RANGO DE 3 A 4,5, ESPECIALMENTE PARA UN VALOR ALREDEDOR DE 3,5; ADEMAS PARA EVITAR O REDUCIR EL EMPOLVORAMIENTO METALICO SE AJUSTA EL GAS DE REDUCCION A UNA RAZON ENTRE 1 Y 3
