Description
The dataset contains the Change of reaction quotients for SOFC fueled by biogas mixture at 750 C (60:40 CH4:CO2). The outlet concentration of the gases from SOFC were measured using novel FTIR-based unit.
Measurement procedure:
"Several approaches concerning equilibrium calculations for methane reforming were already mentioned in other publications [45], [46], [47], [48]. In order to determine the behaviour of each from series of mentioned reactions, a time-dependent thermodynamic analysis was performed using reaction quotients (Qr) [45], [46], [49], which represent a ratio between an actual non-equilibrium constant and equilibrium constant of a specific reaction. Qr value aids in figuring out the momentary direction in which reactions are likely to proceed. Mathematically Qr is calculated from Eq. (24) as a ratio of actual overall partial pressures pi of species "i" raised to the power of stoichiometric coefficient xi (positive for products and negative for reactants) and equilibrium constant Kp,r of discussed reaction. Each of the mentioned reactions was taken into account separately for Qr value estimation in order to simplify the calculation method while providing sufficient enough data for further analysis of equilibrium shifting. All theoretical equilibrium constants Kp were taken from the HSC ChemistryTM software. [...] Quotient indicates if the mentioned reaction goes to the right (for Qr < 1) or to the left (for Qr > 1). When Qr = 1 reaction has reached an equilibrium point. It is commonly approved that Qr∼10−3 stands for the situation when mostly reactants are present in reaction area, while Qr∼103 when nearly all substances are products and finally if 10−3<Qr < 103 then significant amounts of both reactants and products are visible " (10.1016/j.ijhydene.2019.03.243)
