Steam reforming is a method for producing hydrogen gas as a solution for renewable energy generation. One source of hydrogen in a steam reformer is propane gas. The advantage of propane gas is the ease of transportation and storage. The production of hydrogen gas in a steam reformer is certainly influenced by supporting factors such as the temperature of the reformer. In this study, propane steam reforming was simulated in 3D with COMSOL Multiphysics 5.3ª software with bed reformer temperatures varying from 600, 650, 700, 700, 750, 800 and 850 o C with steam to carbon (S/C) ratio 3. The results show that increasing the temperature causes the density of the reformer to decrease, which in turn results in increased gas velocity. In addition, an increase in temperature in the bed reformer increases propane conversion to 87.8% and produces about 40% hydrogen at 850 o C.

Improved electrochemical performance and durability of butane‐operating low‐temperature solid oxide fuel cell through palladium infiltration

Low-operating-temperature solid oxide fuel cells (LT-SOFCs) with various kinds of fuel, such as hydrocarbons, biogas, natural gas, and oxygenated fuel has been an active SOFC research topic. However, conventional SOFC anodes comprised of nickel metal and yttria-stabilized zirconia composite (Ni-YSZ) experience rapid degradation when operated for the butane direct internal steam reforming (B-DISR), especially at a low temperature (LT) range. This study reveals that the impregnated Pd into the Ni-YSZ anode support of thin-film SOFCs (TF-SOFCs) is effective for achieving better performance and stability regarding the TF-SOFC in B-DISR at 600 C. Adding Pd as a dopant into Ni-YSZ significantly promotes the catalytic activity due to the Pd-Ni alloy formation, both on the YSZ grain and the Ni grain surface. The electrochemical performance of cells without Pd (Ni-YSZ cell) and a Pd-infiltrated Ni-YSZ anode (Pd-Ni-YSZ cell) are compared at 600 C for the B-DISR mode at a ratio of steam-to-carbon of 3. Finally, longterm durability tests were performed at 600 C and under 0.15 A cm −2. The Pd infiltration decreases the deterioration rate to 0.63 mV h −1 after the first 80 hours of operation for the Pd-Ni-YSZ cell, which was a significant improvement from that of the Ni-YSZ cell, 3.75 mV h −1 after 40 hours of operation.

“…Therefore, steam reforming of C 3 H 8 (SRP), which typically consists of, but is not limited to, the following main reforming (Eqn (1)) and side water-gas shift (WGS) (Eqn (2)) reactions was studied in this research: Recent investigations have shown that both noble and base metals are very active catalysts for SRP. 15,16 However, noble metals such as Pt, Pd, Rh and Ru are very costly and have limited availability. 3,17 Therefore, many research efforts have been devoted to the use of base metal catalysts, especially nickel (Ni), for SRP.…”

BACKGROUND: The effects of Co and Ce promoters on the performance of Ni (10 wt%)-Co (0.0, 2.75, 5.5 wt%)/Ce (0.0, 5.0, 10.0 wt%)-Al 2 O 3 catalysts have been studied for steam reforming of C 3 H 8 (SRP). In this work, Ni (NO 3) 2 and Co (NO 3) 2 are coimpregnated on the co-precipitated Al 2 O 3-CeO 2 supports. X-ray diffraction, N 2 adsorption-desorption, H 2-temperature-programmed reduction, high-resolution transmission electron microscopy, scanning electron microscopy and thermogravimetric/differential thermal analysis were accomplished to explain the SRP activity of the catalysts. The performance of the resulting catalysts was evaluated under the gas hourly space velocity (GHSV) = 45 000 mL h-1 g cat −1 , T = 600°C, steam/C 3 H 8 ratio (S/C) = 3 and P = 1 atm. RESULTS: The experimental findings revealed that Ce and Co promoters markedly improved the catalyst activity, stability and H 2 yield of Ni/Al 2 O 3 catalyst. The sample with 2.75 wt% Co and 10.0 wt% Ce showed highest C 3 H 8 conversion, while maximum yield of H 2 was obtained for catalyst containing 5.5 wt% Co and 5.0 wt% Ce. CONCLUSION: Higher loadings of Co decreased C 3 H 8 conversion and catalyst stability due to more coke formation on the catalyst surface, whereas Ce significantly improved catalyst resistance to coke deposition due to the enhanced Ni metal particles distribution over the support.
