“…A membrane reactor can be used in CO 2 methanation to enhance the conversion of CO 2 by removing H 2 O from the product mixture (Ashok et al, 2020;Lee et al, 2019b). In other reaction setups, typically at least two reactors are needed for obtaining continuous operation, one is used for the sorption enhanced reaction, another is for the regeneration of the sorbent.…”

“…The CO 2 methanation, also known as the Sabatier reaction, represents—therefore—a fruitful method to mitigate the GHGs and, at the same time, to convert CO 2 into synthetic natural gas (SNG) [ 17 , 18 , 19 ]. Internal combustion engines could use SNG directly as a fuel.…”

In this work, a novel structure of a hydrogen-membrane reactor coupling HI decomposition and CO2 methanation was proposed, and it was based on the adoption of silica membranes instead of metallic, according to their ever more consistent utilization as nanomaterial for hydrogen separation/purification. A 2D model was built up and the effects of feed flow rate, sweep gas flow rate and reaction pressure were examined by CFD simulation. This work well proves the feasibility and advantage of the membrane reactor that integrates HI decomposition and CO2 methanation reactions. Indeed, two membrane reactor systems were compared: on one hand, a simple membrane reactor without proceeding towards any CO2 methanation reaction; on the other hand, a membrane reactor coupling the HI decomposition with the CO2 methanation reaction. The simulations demonstrated that the hydrogen recovery in the first membrane reactor was higher than the methanation membrane reactor. This was due to the consumption of hydrogen during the CO2 methanation reaction, occurring in the permeate side of the second membrane reactor system, which lowered the amount of hydrogen recovered in the outlet streams. After model validation, this theoretical study allows one to evaluate the effect of different operating parameters on the performance of both the membrane reactors, such as the pressure variation between 1 and 5 bar, the feed flow rate between 10 and 50 mm3/s and the sweep gas flow rate between 166.6 and 833.3 mm3/s. The theoretical predictions demonstrated that the best results in terms of HI conversion were 74.5% for the methanation membrane reactor and 67% for the simple membrane reactor.
