|제목||Enhanced catalytic activity of Ni based catalyst promoted alkali metal oxide (MgO, CaO, and La2O3) for CDR reaction|
|초록||A comparative study between Ni−Me−Ce0.8Ze0.2O2 (Me = MgO, CaO, and La2O3) catalysts has been performed in the carbon dioxide reforming of methane (CDR) reaction using simulated biogas that is composed by CH4 and CO2 as 1:1 ratio. The physicochemical properties of catalysts prepared on laboratory were examined by BET, XRD, H2-TPR, and CO2-TPD. Experimental results revealed that Ni−MgO− Ce0.8Ze0.2O2 exhibited excellent catalytic performance (CH4 and CO2 conversion ＞ 96%) at higher temperature (800 oC, GHSV = 480,000 h-1). Furthermore, Ni−MgO− Ce0.8Ze0.2O2 catalyst did not deactivated until 40 hours. As a result, Ni−MgO− Ce0.8Ze0.2O2 catalyst can be considered as a promising catalyst for CDR reaction of biogas.
