Studi Eksperimental Pengaruh Temperatur Water Gas Shift Pada Proses Steam Methane Reforming Terhadap Laju Konversi Karbon Monoksida

Abstract

This study evaluates how operating temperature in the Water Gas Shift (WGS) reactor affects CO conversion efficiency during
hydrogen production via Steam Methane Reforming (SMR). The process involves Reformers, WGS, and Pressure Swing
Adsorption (PSA) for purification. At a WGS reactor temperature of 380°C, CO conversion at the outlet was examined using
a gas mixture of 80% CH4 and 20% CO2, a steam flow rate of 0.15 L/min, and 30 g of FE-CR catalyst. Results showed H2 and
CO2 increased while CO decreased from the reformer to the WGS outlet: CO dropped from 51.37% to 35.68%, H2 rose from
44.90% to 51.84%, and CO2 increased from 3.73% to 12.49%. Higher WGS temperatures accelerate reactant conversion.
