Ni/SBA-15 Catalysts for combined steam methane reforming and water gas shift—Prepared for use in catalytic membrane reactors

Ni-based catalysts (Ni-γ-Al2O3, Ni-HTASO5 and Ni-CeZrOx) were prepared by impregnation method and characterized by BET, AAS, XRD, H2-TPR, CO-TPD, NH3-TPD, XPS, TG-DSC-MS and Raman spectroscopies. Using CeZrOx-modified Al2O3 (HTASO5) as support, the catalyst exhibited good catalytic performance (TOFCH4 = 8.0 × 10−2 s−1, TOFH2 = 10.5 × 10−2 s−1) and carbon resistance for steam-methane reforming (SMR) reaction. Moreover, CeZrOx was able to enhance water-gas shift (WGS) reaction for more hydrogen production. It was found that the addition of CeZrOx could increase the content of active nickel precursor on the surface of the catalyst, which was beneficial to the decomposition of water and methane on Ni-HTASO5. Furthermore, Ni-HTASO5 could decrease the strong acid sites of the catalyst, which would not only contribute to the formation of low graphited carbon, but also decrease the amount of carbon deposition.

Proses pada pabrik bio hidrogen dari bio oil terbagi menjadi beberapa unit, yaitu unit dehidrooksigenasi, unit pemisahan, unit steam reforming, unit water gas shift, dan unit pemurnian. Penelitian ini menjelaskan tentangpengaruh perbandingan komposisi massa metana (CH4) dengan steam (H2O) serta pengaruh perbedaan temperatur pada unit steam methane reforming untuk melihat pengaruh pada produksi bio hidrogen. Penelitian ini dikerjakan menggunakan software simulasi proses Aspen Hysys v.10.0. Dengan menggunakan variabel temperatur pada steam reformer (800 °C, 850 °C, 900 °C, 950 °C, 1000 °C) dan variabel perbandingan komposisi massa steam dengan methane (CH4), yaitu 1:2, 1:1,25, 1:3, 1:3,5, 1:4. Dari penelitian yang dilakukan didapatkan pengaruh komposisi steam dan metana berbanding lurus dengan jumlah bio hidrogen yang dihasilkan. Serta, pengaruh perbedaan temperatur pada reaktor steam reformer berbanding lurus dengan jumlah produksi hidrogen. Dari hasil penelitian didapatkan jumlah produksi bio hidrogen terbaik 1300 kg/jam.Kata kunci: Aspen HYSYS, Bio Oil, Bio Hidrogen
