Catalytic performance of Nickel-M-alumina catalysts (M=Mg and Ca) via n-dodecane autothermal reforming |
| 초록 |
To investigate autothermal reforming(ATR) properties for diesel of Mg(MgNA10-PM) and Ca(CaNA10-PM) catalysts, magnesium and calcium were selected as promoters of Ni-Al based catalysts. These catalysts were prepared by polymer incipient method using PMMA(poly methyl methacrylate). The catalytic activity of the catalysts were carried out in a fixed-bed reactor at 750℃, S/C = 1.23, O2/C = 0.25 and GHSV = 5000~12000h-1. N-dodecane was selected as a surrogate for diesel fuel because it is regarded to have similar properties. MgNA10-PM and NA10-PM catalysts recorded production above 60% hydrogen selectivity and 80% n-dodecane conversion without DBT(dibenzothiophene). In the case of MgNA10-PM catalyst, its hydrogen production and n-dodecane conversion with 100ppm DBT were maintained. But NA10-PM catalyst was deactivated. In the case of CaNA10-PM catalyst, its dodecane conversion was 60% and decreased with 100ppm DBT. The catalysts were characterized by XRD, XPS, SEM-EDS and BET. |
