“…The simulation results demonstrated that the temperature distribution in the reactor considerably changed in the axial and radial directions, and the hydrogen permeability through the membrane varied from position to position in the reactor [19]. On the other hand, few papers deal with exothermic reactions carried out in membrane reactors considering accurately both mass and energy balances [20].…”

“…Tiemersma et al used a detailed numerical simulation study with a 2D reactor model and evaluated different operation modes [16]. In principle, high energy efficiencies could be achieved with a PBMR for autothermal methane reforming, but very large undesired temperature gradients along the reactor were observed when the reactor was operated adiabatically, which are detrimental for membrane stability.…”

Autothermal Reforming of Methane with Integrated CO2 Capture in a Novel Fluidized Bed Membrane Reactor. Part 1: Experimental Demonstration

Two fluidized bed membrane reactor concepts for hydrogen production via autothermal reforming of methane with integrated CO 2 capture are proposed. Ultrapure hydrogen is obtained via hydrogen perm-selective Pd-based membranes, while the required reaction energy is supplied by oxidizing part of the CH 4 in situ in the methane combustion configuration or by combusting part of the permeated H 2 in the hydrogen combustion configuration (oxidative sweeping). In this first part, the technical feasibility of the two concepts has been studied experimentally, investigating the reactor performance (CH 4 conversion, CO selectivity, H 2 production and H 2 yield) at different operating conditions. A more detailed comparison of the performance of the two proposed reactor concepts is carried out with a simulation study and is presented in the second part of this work.

“…Fuel cells are applied in the automotive industry and in power distribution, because of the high energy efficiency of the combination of an electric motor with hydrogen-powered fuel cells (overall efficiency 38-46%), compared to the overall efficiency of the internal combustion engine (10-30%). However, ultra-pure hydrogen (\10 ppm CO) is required because of the sensitivity of the anode catalyst in the PEMFC to CO poisoning [2]. The reactions most commonly used in the production of hydrogen via the steam reforming of hydrocarbons are the high temperature and low temperature water-gas shift reactions (WGSR).…”

The performance of La (1-y) Sr y Ni x Co (1-x) O 3 perovskites for the water gas shift reaction (WGSR) was investigated. The samples were prepared by the co-precipitation method and were performed by the BET method, XRD, TPR, and XPS. The catalytic tests were performed at 300 and 400°C and H 2 O v /CO = 2.3/1 (molar ratio). The sample with the highest surface area is La 0.70 Sr 0.30 NiO 3 . The XRD results showed the formation of perovskite structure for all samples, and the La 0.70 Sr 0.30 NiO 3 sample also presented peaks corresponding to La 2 NiO 4 and NiO, indicating that the solubility limit of Sr in the perovskite lattice was surpassed. The replacement of Co by Ni favored the reduction of the species at lower temperatures, and the sample containing Sr presented the highest amount of reducible species, as identified by TPR results. All samples were active, the Sr containing perovskite appearing the most active due to the highest surface area, presence of the La 2 NiO 4 phase, and higher content of Cu in the surface, as detected by XPS. Among the samples containing Co, the most active one was that with x = 0.70 (60% of CO conversion).
