| Different types of MWO4 (M = Fe, Mn, Ni) were evaluated through thermodynamic analysis and process simulation for the production of hydrogen-synthesis gas (syngas). The partial oxidation (POX) of methane is a more efficient reaction than steam reforming (SMR). However, currently the dominant technology in hydrogen production is through SMR. To overcome one of the most important disadvantages of POX reaction, which deals with the use of pure oxygen as a gas feed, a mixed metal oxide (MWO4, M = Fe, Mn, Ni) is proposed as an oxygen carrier (POX-MeO). The aim of the present study is to evaluate the feasibility of these tungstate metal oxides through the use of thermodynamic analyses and process simulations of an arrangement of two reactors. In the first reactor POX-MeO reactions (CH4 + MWO4 = H2 + CO + M + W; CH4 + MWO4 = H2 + CO2 + M + W) and the undesirable coal formation (CH4 = C + 2H2) are carried out. While in the second reactor, solid products of the first reactor are combined with steam to gasify the previously deposited coal (C + H2O = H2 + CO; C + 2H2O = 2H2 + CO2) and simultaneously regenerate the metal oxide to produce syngas (M + W + H2O = MWO4 + H2). Then, the regenerated oxide is recycled back to the first reactor to make a continuous process. Results of simulation of this process with the different MWO4 oxides are presented using Aspen Plus. | |
