Tri-reforming of CH4 using CO2 for Production of Synthesis Gas to Dimethyl Ether

초록

In this study, we report the results obtained on tri-reforming of methane over the Ni/ZrO2 based catalyst in order to restrain the carbon deposition and to evaluate the catalytic performance. Results of tri-reforming of CH4 by three catalysts (Ni/Ce-ZrO2, Ni/ZrO2 and Haldor Topsoe R67-7H) are showed that the coke on the reactor wall and the surface of catalyst were reduced dramatically. It was found that the weak acidic site, basic site and redox ability of Ce-ZrO2 play an important role in tri-reforming of methane conversion. Carbon deposition depends not only the nature of support, but also on the oxidant as like steam or oxygen.
