“…In this regard, dense Pd membranes with exclusive H2 permeation are preferable when the H2 purity is a priority for MDA in the MR. Therefore, the selection of membrane materials should be carefully Considering the excellent H 2 separation performance of Pd-based membranes, MDA in MRs should be effectively improved after H 2 extraction according to the present and previously reported theoretical simulations [41,42]. However, experimental investigations [25,26,28] have demonstrated that Pd-based MRs show only a very limited enhancement for MDA compared with FBRs under the same operating conditions.…”

“…In this context, the most promising opportunity is expected to come from the utilization of new designs of electrified reactors which are already well adapted for methane pyrolysis. The advantages of this system may arise from employing solid oxide membrane reactor technologies which remove in situ hydrogen while providing additional heat to the process [ 100 , 101 ]. Many of the electrified reactors offer a ‘cold-wall’ design with contact-free heating which avoids a significant radial gradient.…”

“…where α and ε are the absorptivity and emissivity of the collector, taken as 0.9 and 0.1 [42]; σ is Stefan-Boltzmann's constant; T H is the reaction temperature; DNI is the direct normal irradiation; C collector is the concentration ratio of the collector; η s→e is the solar-to-electric efficiency, taken as 15% (commercial photovoltaic (PV) cell efficiency) and 40% (multiplejunction GaAs PV efficiency in laboratory). Q preheat is the heat consumed to raise the temperatures of ethanol and water from room temperature to reaction temperature and is calculated as Equation (4) [31,40]:…”

“…Bai et al experimentally realized an industrial-scale mid-temperature thermochemical power generation using a structure combining a solar thermal collector and a reactor for methanol synthesis [30]. Wang et al [31] modeled a solar dish collector integrated with HPM for non-oxidative methane dehydroaromatization in the temperature range of 600 • C to 800 • C and obtained a theoretical energy efficiency of 85.9%. Tou et al [32] experimentally demonstrated the single-step continuous splitting of CO 2 into separate streams of CO and O 2 under steady-state isothermal/isobaric conditions using a solar-driven ceria membrane reactor.…”
