Combined reforming of methane with carbon dioxide and oxygen in molten carbonate fuel cell reactor

Abstract

An application of a molten carbonate fuel cell (MCFC) system to the reforming reactor is proposed. Molten carbonate is regarded as a permselective membrane for oxygen and carbon dioxide. A combination of partial oxidation of methane with carbon dioxide reforming of methane is possible by applying the MCFC-type reactor as a membrane reactor. The energy of the reaction can be directly converted into electric power. This suggested the possibility of chemicals (syn-gas) and energy (electric power) co-generation and a new way of utilizing carbon dioxide. The selection of the anode catalyst is essential for the reforming reaction. Several transition metals, rare earth metals and noble metals (especially ruthenium) were tested. Among them, nickel was selected as a material for the anode catalyst. The effect of lithium addition was also studied.

Preliminary Assessment of Oxidation Pretreated Hastelloy as Hydrocarbon Steam Reforming Catalyst

“…Our previous works showed the effectiveness of Nibased catalysts with proper additives and supports on dry reforming [14][15][16] and partial oxidation [17,18]. In order to prevent carbon deposition, a strong interaction between Ni 2 Journal of Catalysts and support oxides is required.…”

Evaluation of Preoxidized SUS304 as a Catalyst for Hydrocarbon Reforming

“…Several support materials had been tested, for example, SiO 2 , Al 2 O 3 , ZrO 2 , MgO, olivine, and MgAl 2 O 4 [6][7][8][9][10][11][12][13]. In our previous studies, Ni-based catalysts have been effective both under dry reforming conditions [14,15] and partial oxidation conditions [16,17]. Selection of support materials and additives and arrangement of vacant space to accommodate temporal carbonaceous compounds are essential [14].…”

Preparation of core (Ni base)–shell (Silicalite-1) catalysts and their application for alkali resistance in direct internal reforming molten carbonate fuel cell

“…This can be prevented by separating the catalyst and the anode chamber with ceramic barriers [9,10] and metal foils [11]. There are also significant efforts in developing alkali-resistant catalysts including Ru/ZrO 2 [12] and Ni catalysts supported on alkali-resistant ␥-LiAlO 2 [13], MgO-TiO 2 [14] and MgO-Al 2 O 3 [15]. A nonuniform catalyst distribution can also ameliorate the effects of poisons by locating the catalysts in an interior location of the pellet [16][17][18][19].…”
