| 제목 | Skeletal Ni catalyst prepared under low temperature and its methane steam reforming for hydrogen production application |
| 초록 | The new preparation method has been introduced to synthesis Ni-Al alloy powder using AlCl3 as an activator at relatively low 500~600℃ and vacuum condition. The used AlCl3 served as the catalyst, promoting the reaction between Ni and Al powder to lower down the fabrication temperature by 900~1000℃ compared with that of the conventional process. Ni-Al alloy properties prepared by varying parameters were investigated and the as prepared Ni-Al alloys were alkali leached by NaOH solution for surface modification to prepare the novel skeletal Ni catalyst. Also, the methane steam reforming activity tests were performed at temperature range of 600∼850℃ to investigate the possibility as a catalyst. As results, it was confirmed that the leached Ni50Al alloy shows as good methane conversion and long term stability as that of commercial catalyst and superior H2 yield at low temperature of 600∼750℃. |
