Improved separation of by-product carbon dioxide from nitrogen in power plants and industrial exhaust systems would considerably decrease greenhouse gas emissions. The current method of separation that is most often used in industry is amine absorption, however this method is costly, has a large c…

Post-combustion carbon capture (PCC) provides an option to mitigate CO2 emissions from large stationary sources, followed by compression, transport, and geological sequestration; the captured CO2 may be used for enhanced oil recovery. Because of the system compactness and energy efficiency, CO2-se…

CO2 concentration in the atmosphere has surpassed 400 ppm in the past decade. The combustion of fossil fuels is a major contributor to the large amount of CO2 emission, and membrane technologies have been suggested as a promising approach to capture CO2 from large stationary sources (e.g., flue ga…

Nanoporous polymer substrates are commonly used to provide the mechanical strength for composite membranes in gas separation. The surface property and morphology of the substrate are critical for improving the transport performance of composite membranes. The present invention discloses an effecti…

Membranes are a cost-effective and energy-efficient solution for the separation of carbon dioxide from methane and industrial flue gas. In addition, membranes are utilized to purify hydrogen and syngas. Increased global utilization of natural gas has necessitated efficient natural gas purification…

There has been growing concern about global warming since the CO2 concentration in the atmosphere has surpassed 400 ppm in the past decade. The combustion of fossil fuels is one of the major contributors to the large amount of CO2 emission, and membrane technologies have been suggested as a promis…

Facilitated transport membranes utilize fixed carriers, such as Polyvinylamine (PVAm), and mobile carriers to provide high CO2 permeance and maintain a high CO2/N2 selectivity compared to solution-diffusion membranes. Current production methods of commercial PVAm introduce many problems that can d…

Natural gas and other carbonaceous feedstocks including coal and biomass are the main sources of energy and have been used to produce reformed gas, synthesis gas (syngas), which comprises hydrogen, carbon monoxide, carbon dioxide, and hydrogen sulfide. The syngas, consisting of carbon monoxide, ca…

Industrial processes, such as cement, steel, pulp and paper, chemicals and natural gas processing, are significant emitters of carbon dioxide, which accounts for nearly 25% of energy-related carbon dioxide emissions. The current standard for carbon capture membranes are amine-based, which are susc…

The energy and environmental markets are producing a great research and development race to improve membranes for the fuel cell market to replace petroleum-based energy sources, to improve hydrogen production for use as a fuel in vehicles, and to sequester carbon dioxide to reduce the greenhouse e…
