제목 A study of hydrogen production via SESMR on Ca-Ni-Al-based catal-sorbents: Influence of various precursors
초록 A study for pure H2 production through the CO2 capture in sorption enhanced steam methane reforming (SESMR) has been investigated. To obtain the pure H2, various combination technologies of CaO sorbent had high CO2 capture capacity and Ni-based reforming catalyst in high temperature necessary. In this study, The Ca-Ni-Al-based catal-sorbents was prepared via various co-precipitation methods. The 20 wt% Nickel (II) nitrate, 10 wt % aluminum nitrate and 70 wt % Calcium nitrate were dissolved in 150 mL of distilled water. This solution was stirred at room temperature for 6 h. The various samples were precipitated by adding NaOH (CNAcp_NO), Na2CO3 (CNAcp_NC), NaHCO3 (CNAcp_NHC), respectively, aged for 12 h, and then washed and separated by filtration. The Ca-Ni-Al-based catal-sorbents were carried out in a fixed-bed reactor at 600℃, S/C = 3. The CNAcp_NHC catal-sorbent showed the higher CO2 capture capacity and catalytic activity than the other catal-sorbents. These results were related to pore size, crystal structure and dispersion of Ni active sites of Ca-Ni-Al-based catal-sorbents.
