Syngas production via dry reforming of methane over Ni/MgO-ZrO₂ catalyst

Abstract

This study intended to evaluate the catalytic activity of Ni/MgO-ZrO2 to produce syngas through dry reforming of methane (DRM). The catalyst was prepared by using co-precipitation method followed by impregnation of Ni metal. XRD, BET and FESEM were used to analyze the physicochemical characteristics of the prepared catalyst. A stainless steel vertical reactor fixed with a catalyst bed inside was used to run the DRM process at 800°C, 1 atm and 1:1:1 ratio of CO2:CH4:N2. From the three catalysts studied, Ni/MgO-15%ZrO2 had the maximum conversion for CH4 and CO2 compared to the other two catalysts. The high conversion achieved was because of zirconium oxide. The result obtained from the DRM reaction was further supported by the characterization results, which included average particle size, the morphology of the catalyst, and catalyst peaks.
