| 제목 | Effect of antimony additives on the nickel based catalysts for steam-carbon dioxide reforming of methane |
| 초록 | Reforming of methane has been studied in detail, because of the possibility of converting to useful syngas, which can be further converted into synfuel and chemicals. The present study was conducted to figure out the resistence of carbon deposit by adding Sb over Ni/γ-Al2O3 catalyst in steam-CO2 reforming of methane (CSCRM) to produce synthesis gas (H2/CO = 2) for gas to liquid(GTL). Alumina supported nickel catalysts were prepared using the impregnation method and alumina was impregnated with 12 wt% of Ni. The catalytic reaction was conducted at 900 °C, 1 atm with feed ratio of CH4 : CO2 : H2O : Ar = 1 : 0.8 : 1.3 : 1 and WHSV = 40,000 h-1. The synthesized catalysts were characterized by N2 Adsorption Desorption, X-ray diffraction (XRD), H2-temperature programmed reduction (H2-TPR), Thermogravimetric analysis (TGA) and Scanning Electron Microscope (SEM). As a result, Sb modified Ni-Mo/γ-Al2O3 catalysts suppressed the carbon deposition also improved the catalytic activity. |
