“…For example, large-scale carbon capture and sequestration (CCS) plants rely on solvent scrubbing systems that have struggled to make meaningful improvements on the monoethanolamine baseline performance. 2 This, despite the numerous publications reporting higher performance systems based on pressure/temperature swing processes and membrane technologies for CO 2 capture. [3][4][5][6] Membrane technology's potential to greatly reduce the energy costs of separation processes is not being realized.…”

Physical aging in glassy mixed matrix membranes; tuning particle interaction for mechanically robust nanocomposite films

Despite the exceptional separation performance of modern glassy mixed matrix membranes, these materials are not being utilized to improve the performance of existing membrane technologies. Nano-sized additives can greatly enhance separation performance, and have recently been used to overcome age-related performance loss of high performance MMMs. However nano-additives also compromise the structural integrity of films and little is known on how physical aging affects their mechanical properties over time. A solution for both physical aging and mechanical instability is required before these high performance materials can be utilised in industrial membrane applications. Here, we examine physical aging in mixed matrix membranes through mechanical properties and single gas permeation measurements using three glassy polymers, Matrimid® 5218, poly-1-trimethylsilyl-1-propyne (PTMSP), and a Polymer of Intrinsic Microporosity (PIM-1); and a range of nano-scale additives; Silica, PAF-1, UiO-66, and Ti5UiO-66, each previously shown to enhance gas separation performance. We find polymer-additive interactions strongly influence local physical aging and play a key role in determining the overall material properties of glassy nanocomposite films. Strong interface interactions can slow physical aging, and may not correlate to reinforced or age-stable films. Whereas traditionally 'incompatible' nanocomposites exhibit mechanical properties that can improve over time and even outperform their native polymers.Tuning polymer-additive interactions is vital to achieving the physical aging, mechanical stability, and permselectivity requirements of advanced mixed matrix membrane technologies and reducing the enormous global energy cost of separation processes.

The Role of Ruthenium in CO2 Capture and Catalytic Conversion to Fuel by Dual Function Materials (DFM)

Development of sustainable energy technologies and reduction of carbon dioxide in the atmosphere are the two effective strategies in dealing with current environmental issues. Herein we report a Dual Function Material (DFM) consisting of supported sodium carbonate in intimate contact with dispersed Ru as a promising catalytic solution for combining both approaches. The Ru-Na 2 CO 3 DFM deposited on Al 2 O 3 captures CO 2 from a flue gas and catalytically converts it to synthetic natural gas (i.e., methane) using H 2 generated from renewable sources. The Ru in the DFM, in combination with H 2 , catalytically hydrogenates both adsorbed CO 2 and the bulk Na 2 CO 3 , forming methane. The depleted sites adsorb CO 2 through a carbonate reformation process and in addition adsorb CO 2 on its surface. This material functions well in O 2 -and H 2 O-containing flue gas where the favorable Ru redox property allows RuO x , formed during flue gas exposure, to be reduced during the hydrogenation cycle. As a combined CO 2 capture and utilization scheme, this technology overcomes many of the limitations of the conventional liquid amine-based CO 2 sorbent technology.Keywords: supported Ru and sodium carbonate; dual function material; CO 2 capture in flue gas; conversion to synthetic natural gas; redox properties of Ru

“…The major culprit for in the increase in CO 2 in the atmosphere is the utilization of fossil fuel for energy generation and trasnportation. Several strategies is been used to reduce or prevent further release of CO 2 such as improvement in the technology, energy conservation, utilization of renewable technology and CO 2 sequestration [2].…”

Abstract. This study evaluates the performance of alkaliphilic microalgae Ankistrodesmus falcatus in the Bicarbonate-based Integrated Carbon Capture and Algae Production System (BICCAPS). The system utilized bicarbonate as carbon source for microalgae production. BICCAPS parameters such as pH, algal biomass productivity and CO2 utilization (inorganic carbon conversion, Ci) were observed at different sodium bicarbonate (NaHCO3) loading concentration and type of culture media. The highest productivity was observed at 10 g/L of NaHCO3 loading in BRSP medium at 3.5539 mg/L/day. This value is 30% lower compared to the control experiment (continuously aerated bioreactor). The Ci values of the different system ranges from 1.17 x 10 -4 to 1.51 x 10 -4 moles/L/day. Both the pH of the BRSP and NPK media at 10 g/L and 30g/L loading of NaHCO3 increased through time. The result shows that A. falcatus has a potential in BICCAPS utilization.
