dc.description.abstract | We performed a methane steam reforming (MSR) reaction through a membrane reactor packed with commercial Ni/Al2O3 catalyst and a tubular Pd-Ru membrane deposited on a YSZ modified porous stainless steel support under mild operating conditions: 773 K and a pressure difference range of 100-250 kPa. We prepared the Pd-Ru membrane with thickness of similar to 6 mu m on a tubular stainless steel support (diameter 12.7mm, length 25 cm) using electroless plating, which was observed for the membrane performance using hydrogen and nitrogen. Gas permeation test carried out at 773 K and 31.4 kPa of pressure difference between retentate and permeate sides showed that the hydrogen permeation rate and nitrogen leakage were similar to 0.1050mol s(-1) m(-2) and similar to 0.0018 mol s(-1) m(-2), respectively. The MSR reaction was under the following conditions: temperature 773 K, pressure 100-250 kPa, gas hourly space velocity (GHSV) 837 h(-1), and steam-to-carbon feed ratio (S/C) 3. The MSR reaction result showed that methane conversion was increased with increasing pressure difference and reached similar to 77.5% at 250 kPa. In this condition, the composition of carbon monoxide was similar to 2%, meaning that no two series of water gas shift reactors were needed in our membrane reactor system. Longterm stability test carried out for similar to 100 h showed that methane conversion and the hydrogen yield remained constant. | - |
