합성가스 제조를 위한 CO2/수증기에 의한 메탄 개질반응 연구 = The Study on Methane Reforming by CO2 and Steam for Manufacture of Synthesis Gas

다국어 초록 (Multilingual Abstract)

The methane reforming with CO2 and steam for manufacture of synthesis gas over Ni/ZrO2 catalyst was investigated. Mixed reforming carried out CO2 dry reforming with O2 and steam for development of DME process in pilot plant. To improve a catalyst deactivation by coke formation, the mixed reforming added carbon dioxide and steam as a oxidizer of the methane reforming was suggested. The result of experiments over commercial catalyst in CO2 dry reforming has shown that the catalyst activity decrease rapidly after 20 hours. In case of NiO-MgO/Al2O3 catalyst, the deactivation of 20 percent after 30 hours was occurred. The activity of Ni/ZrO2 catalyst still was not decreased dramatically after 100 hours. The effect of CO2 reforming with steam over Ni/ZrO2 catalyst obtained the optimal conversion of methane and carbon dioxide, and could be produced synthesis gas at ratio of H2/CO under 1.5.
