Studi Eksperimental Pengaruh Steam to Carbon Ratio 4:1 Terhadap Produksi Hidrogen Pada Reformer Melalui Proses Steam Methane Reforming

Abstract

Fossil energy still supports activities in various sectors, but its constraints encourage exploration to find sustainable alternative
energy. Hydrogen (H2) is a renewable energy that has a lot of potential with its advantages. Steam methane reforming (SMR)
is a dominant H2-producing technology used on an industrial scale with two process stages, namely reformer and water gas
shift (WGS). Steam to carbon ratio (S/C) is one of the important parameters in determining the H2 produced in the reformer.
This study aims to determine the effect of S/C on H2 production in a reformer reactor with S/C 4:1, input gas composition of
70% methane (CH4) and 30% carbon dioxide (CO2), 30 grams of MgNi catalyst, set temperature of 500°C, and pressure of 1
atm. The results show that the 4:1 S/C is able to convert CH4 and CO2 by 70% and 17.96% respectively to produce H2, CO,
and residual CO2 by 43.82%, 44.14%, and 12.04% respectively. This shows the role of S/C 4:1 which is able to better shift the
reaction equilibrium towards the formation of products in the form of H2.
