“…There are several technologies that have been proposed to tackle the problem of CO2 emissions: carbon capture and storage technologies [4,5], absorption methods based on amine solutions [6] or solid minerals [7][8][9]. Both carbon capture & storage and solvent scrubbing towers technologies require high capital investments, whereas reverse absorption of CO2 by freely available and cheap solid catalysts (various minerals, CaO, MgO, mixed oxides) can be considered as more commercially attractive technology.…”

Several problems with stabilization of electricity grid system are related to the time lag between the electricity supply and demand of the end users. Many power plants run for a limited period of time to compensate for increased electricity demand during peak hours. The amount of CO2 generated by these power installations can be substantially reduced via the development of new demand side management strategies utilizing CO2 absorption units with a short start-up time.The sorbent can be discharged using radiofrequency (RF) heating to fill the night-time valley in electricity demand helping in the stabilization of electricity grid. Herein a concept of RF heated fixed bed reactor has been demonstrated to remove CO2 from a flue gas using a CaCO3 sorbent. A very stable and reproducible operation has been observed over twenty absorptiondesorption cycles. The application of RF heating significantly reduced the transition time required for temperature excursions between the absorption and desorption cycles. The effect of flow reversal during desorption on desorption time has been investigated. The desorption time was reduced by 1.5 times in the revered flow mode and the total duration of a single absorption-desorption cycle was reduced by 20%. A reactor model describing the reduced desorption time has been developed. 2 Highlights• An RF reactor system has been demonstrated for post-combustion carbon capture.• The transition time between the absorption and desorption cycles was reduced by 2 times as compared to conventional heating• The reverse CO2 desorption flow mode reduced the desorption time by 1.5 times.• The energy efficiency of RF heated and conventionally heated bench reactors was compared

“…Bhatta et al reviewed the progress in hydrotalcite like compounds and metal-based oxides for CO 2 capture in SERP for H 2 production and removal of CO 2 from hot flue gas/syngas. Further, the various pros and cons of property enhancement methods are discussed and some conclusions are made along with suggestions for future work [18]. This paper discussed the main characteristics and preparation methods of solid sorbents for in situ CO 2 removal in SERP, and the available techniques for improvement of their behavior for high purity hydrogen production from SERP are presented.…”

“…Therefore, another category of membrane called mixed matrix membrane (MMM) is studied, which possesses both the properties of polymeric and inorganic materials . Extensive works have been performed on MMMs using various nanosheets, nanotubes, and nanoparticles . Hydrotalcite (HT) has been found to excel in terms of efficient CO 2 capture ability due to carrier availability and memory effect characteristic .…”

A comprehensive understanding of carboxymethyl chitosan (CMC)‐based mixed matrix membrane (MMM) has been critically investigated. The present work elaborates the compatibility of hydrotalcite (HT) and CMC in terms of CO2 separation application. Various spectroscopic and microscopic techniques have been utilized to characterize the respective properties of the prepared membrane. The temperature stability and moisture retention behavior of the membrane recognized itself as the flue gas separation membrane. The CO2/N2 separation experiment was performed on the MMM at different temperature (60–110 °C) and sweep/feed water flow to the saturator ratio (0.33 to 3). The membrane exhibited the optimum CO2 permeance of 70 GPU at 90°C pertaining to water flow ratio of 2.33 (sweep/feed). The CO2/N2 selectivity observed at that same operating condition was 13. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2020, 137, 48715.
