CO2 reforming reaction assisted with oxygen permeable Ba0.5Sr0.5Co0.8Fe0.2Ox ceramic membranes

Rapid glycine-nitrate combustion synthesis of the CO2-stable dual phase membrane 40Mn1.5Co1.5O4−δ–60Ce0.9Pr0.1O2−δ for CO2 capture via an oxy-fuel process

“…However, the development of the 4-end membrane operation mode technology is hampered since the state-of-the-art OTMs suffer from low chemical stability toward corrosive components of the flue gas such as CO 2 and SO 2 , which lead to a poor oxygen permeation performance and even membrane destruction [9][10][11][12][13][14]. It is known that single phase perovskite-type OTM materials (ABO 3 ) with a high content of alkaline-earth metals on the A site, easily react with CO 2 and SO 2 forming carbonates and sulfates [15][16][17][18].…”

Chemical looping and oxygen permeable ceramic membranes for hydrogen production – a review

“…In this process the two are co-fed into the same membrane compartment and oxygen is provided by the OTM as for the POM process. Table 5 lists five such studies since 2004 144,146,147,190,202 . ceria-based oxides as catalyst supports.…”

“…It was concluded that the POM products diffused through the quartz wool and consumed the oxygen permeate at the membrane surface providing a mechanism to improve permeation and 65 indicating that oxygen spillover played no significant role. In a similar study using a Ba 0.5 Sr 0.5 Co 0.8 Fe 0.2 O x OTM with platinum supported on ceria zirconate for the dry reforming of methane with carbon dioxide, it was found that the carbon dioxide conversion was greater with intimate contact between the catalyst 70 and OTM 144 . It was also put forward that a synergy between the two existed in which the high oxygen flux provided by Ba 0.5 Sr 0.5 Co 0.8 Fe 0.2 O x acted to stabilise the reforming catalyst through oxygen spillover by preventing reduction of Ce 4+ to Ce 3+ .…”

Adsorptive removal of carbon dioxide using polyethyleneimine loaded glass fiber in a fixed bed

“…The CO 2 emissions related to the energy sector will further increase by 130% by 2050 due to increasing fossil fuel usage [4,5]. Currently, chemical absorption [6][7][8], membrane [9,10], ionic liquids [11,12] and cryogenic techniques have been investigated for CO 2 capture. Among these technologies, aqueous amine chemical absorption systems including monoethanolamine and diethanolamine [13,14] have been commercially utilized for CO 2 capture from power plant effluents.…”
