H2O-enhanced CO2 transport through a proton conducting ceramic- molten carbonate dual-phase membrane

An asymmetric tubular ceramic-carbonate dual phase membrane for high temperature CO2 separation.

For the first time, a tubular asymmetric ceramic-carbonate dual phase membrane was prepared by a centrifugal casting technique and used for high temperature CO2 separation. This membrane shows high CO2 permeation flux and permeance.

CO2‐Tolerant SrFe0.8Nb0.2O3−δ−Carbonate Dual-Phase Multichannel Hollow Fiber Membrane for CO2 Capture

Ceramic−carbonate dual-phase membranes have attracted a lot of attention because of the emission of CO2 and environmental problems. In this study, a dense SrFe0.8Nb0.2O3−δ−carbonate dual-phase multichannel hollow fiber membrane has been successfully prepared via a phase inversion−sintering technique and impregnation. The morphology, crystal structure, phase stability, breaking load, and CO2 per...

Molten Carbonate Fuel Cells

Molten carbonate fuel cells use carbonate salts of alkali metals as electrolyte. Due to the highly corrosive nature of the electrolyte, various countermeasures are being developed. MCFCs are expected for high-efficiency power generation systems using hydrocarbon fuels, such as natural gas and coal gas. This article describes the mechanisms of operation and cell degradation, as well as the featu...

CO2 Capture by Dual Hollow Fiber Membrane Systems

In this paper, a system for efficient removal of carbon dioxide by hollow fiber membranes is proposed. The system is compact, and it is very useful for application in the offshore energy industries. In particular, it is used to removing CO2 from the exhaust of power generation facilities on offshore platforms.The proposed dual membrane contactor contains two types of membranes (polypropylene me...
