“…Numerous novel inorganic materials with different effects on the gas transport properties of polymeric membranes have been identified. Substantial improvements in gas separation performance have been observed with inorganic fillers, such as carbon and carbon-based oxides [ 16 ] and zeolites [ 17 ]. Nonporous fillers such as silica [ 18 ], clay particles [ 19 ] and metal oxides [ 9 , 20 ] have also had beneficial effects on the gas separation performance.…”

Due to the high affinity of ceria (CeO2) towards carbon dioxide (CO2) and the high thermal and mechanical properties of cellulose triacetate (CTA) polymer, mixed-matrix CTA-CeO2 membranes were fabricated. A facile solution-casting method was used for the fabrication process. CeO2 nanoparticles at concentrations of 0.32, 0.64 and 0.9 wt.% were incorporated into the CTA matrix. The physico-chemical properties of the membranes were evaluated by SEM-EDS, XRD, FTIR, TGA, DSC and strain-stress analysis. Gas sorption and permeation affinity were evaluated using different single gases. The CTA-CeO2 (0.64) membrane matrix showed a high affinity towards CO2 sorption. Almost complete saturation of CeO2 nanoparticles with CO2 was observed, even at low pressure. Embedding CeO2 nanoparticles led to increased gas permeability compared to pristine CTA. The highest gas permeabilities were achieved with 0.64 wt.%, with a threefold increase in CO2 permeability as compared to pristine CTA membranes. Unwanted aggregation of the filler nanoparticles was observed at a 0.9 wt.% concentration of CeO2 and was reflected in decreased gas permeability compared to lower filler loadings with homogenous filler distributions. The determined gas selectivity was in the order CO2/CH4 > CO2/N2 > O2/N2 > H2/CO2 and suggests the potential of CTA-CeO2 membranes for CO2 separation in flue/biogas applications.

Keeping certain level of carbon dioxide concentration along with a desired oxygen concentration in food packages is helpful in preserving a variety of foods, and thus, active packaging technology to control CO 2 has been reviewed here in perspective of optimized package design. For whatever product packages, tailoring interaction among the gas, food product and packaging material is essential for realization of positive role and function of CO 2 : antimicrobial activity, prevention of oxidation, preferred sensory quality, maintenance of package integrity and extension of shelf life.Gas absorbers, emitters or active valves may be applied for this purpose, and commercial products are available in market. However, these active devices should be applied in harmony with food's CO 2 production and dissolution. Elements or factors involved in the design process are examined by looking over scientific literature.Mass balance relationship combined with dissolution equilibration for active food package has been presented to control CO 2 concentration and package wholesomeness in beneficial and desired way. Atmosphere estimation of roasted coffee packages was presented as case study for tackling the task of attaining the desired condition.

“…Using porous micro-or nano-sized fillers in a polymer to improve its permselectivity was first used in the early 1990s for gas and vapor separation [22][23][24]. Zeolites [24,25], carbon nanotubes (CNT) [26], silica [27,28], fullerenes [29], and metalorganic frameworks (MOFs) [30,31] are commonly incorporated or dispersed into the polymeric matrix to form MMMs. MOFs attract much attention as porous fillers due to their high porosity, adjustable pore size, and rich chemical functionality.…”

CO2/CH4 and H2/CH4 Gas Separation Performance of CTA-TNT@CNT Hybrid Mixed Matrix Membranes

et al. 2021

This study explored the underlying synergy between titanium dioxide nanotube (TNT) and carbon nanotube (CNT) hybrid fillers in cellulose triacetate (CTA)-based mixed matrix membranes (MMMs) for natural gas purification. The CNT@TNT hybrid nanofillers were blended with CTA polymer and cast as a thin film by a facile casting technique, after which they were used for single gas separation. The hybrid filler-based membrane depicted a higher CO2 uptake affinity than the single filler (CNT/TNT)-based membrane. The gas separation results indicate that the hybrid fillers (TNT@CNT) are strongly selective for CO2 over CH4 and H2 over CH4. The increment in the CO2/CH4 and H2/CH4 selectivities compared to the pristine CTA membrane was 42.98 from 25.08 and 48.43 from 36.58, respectively. Similarly, the CO2 and H2 permeability of the CTA-TNT@CNT membrane increased by six- and five-fold, respectively, compared to the pristine CTA membrane. Such significant improvements in CO2/CH4 and H2/CH4 separation performance and thermal and mechanical properties suggest a feasible and practical approach for potential biogas upgrading and natural gas purification.
