Hydrogen is a promising alternative fuel to establish environmentally friendly energy generation system. One of the methods for producing hydrogen is C02 methane reforming (CMR) process. Despite producing H2, this process also consumes CO2 enabling it to be used as a scheme for mitigating CO2. Conventionally, the hydrogen production via CMR is conducted in a fixed bed reactor. However low conversion is usually found in this kind of reactor. To increase conversion, a membrane reactor can be used. Two types of membrane may be employed to conduct this reaction, i.e. prorous  vycor and nanosil membrane  reactor.  This study  evaluated the  performances  of CMR con 1ucted in membrane ractors andfixed-bed reactor. The results show that the conversion obtained in nanosil membrane reactor is higher than those obtained in porous vycor membrane reactor and fixed-bed reactor. With the change in reactant flowrate, it is obtained that the conversions in membrane reactors are more stable than those infixed bed reactors.Keywords: Hydrogen Production, Membrane Reactor, Methane Reforming AbstrakHidrogen merupakan bahan bakar alternatif yang sangat menjanjikan untuk sistem pembangkitan energi yang lebih ramah lingkungan. Salah satu rute produksi hidrogen adalah melalui reformasi metana dengan karbondioksida (C02 Methane Reforming/CMR). Saat ini telah dikembangkan proses CMR menggunakan membran yang mampu meningkatkan laju produksi H2• Pada makalah ini dikaji dua tipe reaktor membran untuk maksud peningkatan produksi hidrogen tersebut, yakni reaktor membran dengan basis membran porous vycor dan nanosil. Sebagai pembanding, dilakukanjuga evaluasi unjuk kerja reaksi CMRpada reaktorfzxe-bed. Hasil kajian ini menurljukkan bahwa reaktor nanosil danporous vycor mampu memberikan konversiyang lebih besar dibanding reaktor fixed-bed. Lebihjauh, reaktor membran dengan nanosil membran mampu memberikan laju produksi hidrogen yang lebih tinggi dibanding reaktor membran dengan membran porous vycor. Lebih jauh, pada perubahan laju molar reaktan, reaktor membran menurijukkan stabilitas yang lebih baik dibanding reaktor fixed-bed.Kata Kunci: Produksi Hidrogen, Reaktor Membran, Reformasi Metana

AbstractMembrane reactors are attracting increasing attention for ultrapure hydrogen production from fossil fuel, integrating catalytic reaction and separation processes into one single unit thus can realize the removal of hydrogen or introduction of reactant in situ, which removes the thermodynamic bottleneck and improves hydrogen yield and selectivity. In this review, the state-of-the-art concepts for hydrogen production through membrane reactors are introduced, mainly including fixed bed membrane reactors, fluidized bed membrane reactors, and micro-channel membrane reactors, referring higher hydrocarbons as feedstock, such as ethanol, propane, or heptane; novel heating methods, like solar energy realized through molten salt; new modular designs, including panel and tubular configurations; ultra-compact micro-channel designs; carbon dioxide capture with chemical looping; multifuel processors for liquid and/or solid hydrocarbons; etc. Recent developments and commercialization hurdles for each type of membrane reactor are summarized. Modeling the reactor is fundamental to explore complex hydrodynamics in reactor systems, meaningful to investigate the effects of some important operating factors on reactor performances. Researches for reactor modeling are also discussed. Reaction kinetics for hydrocarbons reforming and reactor hydrodynamics are summarized respectively. Cold model is introduced to investigate physical phenomena in reactors.
