Abstract

Produksi hidrogen melalui reformasi uap metana (Steam Methane Reforming / SMR) memerlukan pengendalian kondisi operasi yang tepat karena sifat reaksinya yang sangat endotermik. Penelitian ini bertujuan untuk mengoptimasi produksi dan purifikasi hidrogen dalam reaktor mikrokanal melalui pendekatan simulasi dan eksperimental menggunakan DWSIM dan ASPEN Plus. Parameter operasi yang dikaji meliputi temperatur reformer, tekanan, rasio steam-to-methane (S/C), dan suhu cooler. Hasil penelitian menunjukkan bahwa temperatur reformer merupakan faktor paling dominan, dengan kondisi optimal pada suhu sekitar 900 °C, tekanan 16 bar, dan rasio S/C sebesar 2, yang menghasilkan fraksi mol hidrogen sekitar 43,56% pada tahap reformasi. Pengaturan suhu cooler berperan dalam menyiapkan kondisi proses lanjutan tanpa memengaruhi komposisi gas secara langsung. Hasil ini menegaskan potensi reaktor mikrokanal sebagai sistem produksi hidrogen yang efisien dan aplikatif.

Hydrogen production via steam methane reforming (SMR) requires precise operating control due to its highly endothermic reaction characteristics. This study aims to optimize hydrogen production and purification in a microchannel reactor through simulation and experimental approaches using DWSIM and ASPEN Plus. The investigated operating parameters include reformer temperature, operating pressure, steam-to-methane (S/C) ratio, and cooler temperature. The results indicate that reformer temperature is the most influential parameter, with optimal conditions achieved at approximately 900 °C, 16 bar pressure, and an S/C ratio of 2, producing a hydrogen mole fraction of about 43.56% at the reforming stage. Cooler temperature plays a supporting role in preparing the gas for downstream processes without directly affecting gas composition. These findings demonstrate the potential of microchannel reactors as efficient and practical systems for small- to medium-scale hydrogen production.
