“…The kinetic diameter of N 2 and CH 4 was 364 and 380 pm respectively. Hence, the separation factor of CO 2 /CH 4 was taken to be more than 1000 6 . In this case, the permeance of CH 4 could be neglected.…”

The membrane exhibits high CO 2 selectivity and permeability, which is about 25 times more effective than the previously reported carbonate‐ceramic dual‐phase membranes.…”

“…One of the factors that contribute to the membrane performance is the transportation of ions (O 2− and CO 3 2− ions) in the liquid (molten) phase instead of oxide conducting solid phase material. This enables a lower operating temperature compared to the carbonate‐based dual‐phase membrane, in addition to the improvement of the overall CO 2 flux, which enhances the CO 2 permeance 6 . Thus, HCDP membrane operates at the desirable natural gas temperature, eliminating additional heating and cooling steps that are required by other membranes.…”

CO 2 capture and natural gas purification are of paramount significance in power plant applications nowadays. Dual-phase membrane is an effective approach for the enhancement of CO 2 /CH 4 separation efficiency. In this study, CO 2 /CH 4 binary gas mixture separation was simulated by using hydroxide/ceramic dual-phase (HCDP) membranes incorporated in the industrial-scaled tubular membrane module. Computational fluid dynamics (CFD) was utilized as the approach to model the fluid flow within the membrane module. Utilizing the CFD modeling of membrane module, the effects of tubular membrane thickness, operating temperature and CO 2 feed concentration on the separation performance of HCDP membrane had been investigated.The results showed that membrane thickness affected the effective surface area of the membrane and CO 2 permeance. The greater the membrane thickness, the lower was the membrane separation efficiency. The highest CO 2 recovery obtained was 90.12% at 1 mm tubular membrane thickness, with the membrane stage cut ratio of 0.1950. Operating temperature imposed a notable influence on the gas permeance as well. By increasing the operating temperature, CO 2 permeances were improved and hence, the separation performance of HCDP membrane was enhanced simultaneously. As for the effect of CO 2 feed concentration on the membrane performance, it was found that the overall membrane performance and separation efficiency were better when the CO 2 feed concentration was low, due to the higher availability of the adsorption sites on the membrane surface. In conformity with the membrane technology as a cost-effective CO 2 sequestration technique, the dual-phase membrane has demonstrated a remarkable potential to be adopted for industrial applications.

Solar energy is one of the most abundant, clean, and widespread energy in the world, which has the potential to address the issues of environmental pollution, global warming, and energy crisis, while the intermittent distribution of solar energy in time and space limits its utilization. Among various approaches of solar energy utilization, converting solar energy into chemical fuel (e.g., hydrogen) by thermochemical approach could maintain the steady and high-efficient energy supply and can make use of the full-spectrum solar energy. The research about solar thermochemical fuel generation lasts more than 40 years, and lots of reaction system and reactors have been proposed. This chapter reviews the state-of-the-art progress of solar thermochemical fuel generation, and the characteristics of different systems have been compared and discussed, which may give systematical insight into the development and improvement of solar fuel generation by thermochemical approach in the future.

Mixed oxygen ionic‐carbonate ionic conductor membrane reactor for coupling CO₂ capture with in situ methanation

CO 2 methanation is one of the vital reactions to utilize CO 2 and realize power to gas process. To decrease the CO 2 capture cost and alleviate the hot spots during the strong exothermic methanation reaction, here, we report a coupling of CO 2 capture process with in situ CO 2 methanation process through a ceramic-molten carbonate (MC) dual phase membrane reactor over the Ni-based catalyst. The performance of the membrane reactor was systematically investigated and compared with the traditional fixed-bed reactor. The results show that the performance of the membrane reactor is higher than that of the fixed-bed reactor, since the produced steam through the methanation process can be partially removed through the dual-phase membrane, which promotes the reaction shift to right side. A stability test shows no obvious degradation within 32 h. These results indicate that the membrane reactor is promising for coupling CO 2 capture with in situ methanation process.
