제목 Catalytic Effect of metalpromoters on Co/Al2O3 in the CO2 dry reforming with methane
초록 Carbon dioxide reforming of methane has been studied over Co/Al2O3 catalyst promoted with different metal additives(Ru, Ir, La, Ce, Zr) for improving catalysts performance and preventing coking.
BET, XRD, ICP Mass, EDS and TEM were applied for sample characterization and dry reforming of methane was carried out a feed mixture consisted of CH4/CO2/N2=40/40/20 ratio. The amount of deposited carbon on used catalysts was determined after ca. 20hr of time on stream reaction at 973K with 20,000ml/gcat·hr.
Different activity levels of the catalysts clearly show that the type of the promoter significantly affected the metal dispersion properties and catalytic performances of Co/Al2O3 catalysts. Co/Al2O3 catalyst of modified Ru-Zr exhibited the highest activity and stability among all thecatalysts prepared.
