To investigate performance of alumina-supported Ni(NA10-PM) and Ru(R5Al) catalysts for n-dodecane autothermal reforming, it were carried out in a fixed-bed reactor at 500~750°C, S/C = 0.5~3, O2/C= 0.1~0.25 and GHSV = 5000~12000h-1. N-dodecane was used to surrogate diesel fuel because it is regarded to have similar properties. NA10-PM catalyst was prepared by porous material method using PMMA (poly methyl methacrylate). A commercial catalyst (R5Al) was used in this study. The catalyst showed various catalytic activities according to the conditions. The NA10-PM catalyst exhibited the higher H2 yield, CO yield and dodecane conversion than R5Al. The catalysts were charaterized by XRD and XPS. But all of two catalysts were deactivated when sulfur was present. The other analysis like SEM-EDS, BET and TPR were also coducted to characterize catalysts. |
