Polymer-based membranes play a key role in several industrially important gas separation technologies, e.g., removing CO2 from natural gas, with enormous economic and environmental impact. Here, we develop novel hybrid membrane construct comprised entirely of nanoparticles grafted polymers. These are shown to have broadly tunable performance through variations graft density chain length. Computer simulations show that the optimal NP packing forces polymer layer distort, yielding regions...
Polymer membranes are critical to many sustainability applications that require the size-based separation of gas mixtures. Despite their ubiquity, there is a continuing need selectively affect transport different mixture components while enhancing mechanical strength and hindering aging. Polymer-grafted nanoparticles (GNPs) have recently been explored in context separations. Membranes made from pure GNPs higher permeability lower selectivity relative neat polymer because they increased mean...
The article provides a short review on catalyst-based processes for the production of hydrogen starting from methane, both fossil origin and sustainable processes. three main paths steam- dry-reforming, partial oxidation thermo-catalytic decomposition are briefly introduced compared, above all with reference to latest publications available new catalysts which obey criteria lower environmental impact minimize content critical raw materials. novel strategies based chemical looping CO2...
In this work, three metakaolin-based geopolymer matrices were prepared, varying the molar ratio Si:Al (2.0 or 1.2) and type of cation (sodium potassium). Starting from these matrices, geopolymer-zeolite composites synthesized consolidated (80 °C), incorporating a commercial sodium-based zeolite, Na4A, with aim producing post combustion CO2 adsorbents, since presence Na4A crystalline phase is desirable due to its known remarkable adsorption capacity. The matrix = 1.2 allowed in situ...
The separation and removal of CO2 from its mixtures with CO is gaining increasing interest due to the novel processes in which these two gases are mixed, such as non-thermal plasma activated reaction splitting, a promising utilisation route that could be performed using renewable energy. aim this review propose database suitable for membrane scientists evaluate feasibility membrane-based involving gas mixture, not included original Robeson's works on upper bound nor later developments. For...
The estimation of the solubility fluid mixtures in polymeric phases is an essential prerequisite for membrane separations and design several devices, such as chemical sensors: presence swelling strongly interacting components mixture can often cause rather large deviations from pure component sorption behavior. For rubbery polymers, usual equilibrium tools multicomponent versions equation state (EoS) models be adopted, while case glassy which are not at equilibrium, approach cannot followed....
The sorption of organic vapors different chemical nature, molecular weight and polarity in glassy Matrimid 5218 polyimide films is measured modeled the entire activity range up to saturated vapor conditions. Experimental isotherms show several peculiarities according nature solute component, consistent with character polymeric matrix. These features from high solubility coefficient at infinite dilution swelling plasticization polymer matrix depending on temperature affinity. various...
The analysis and modeling of the sorption behaviors in glassy polymers, gases vapors particular, is crucial relevance for a variety different applications. Due to peculiar associated with nonequilibrium character polymer glasses, approaches have been used so far describe gas solubility, whose dependence on penetrant pressure or activity shows broad spectrum experimental behaviors. In this work, three commonly completely (the Dual Mode Sorption (DMS), based simultaneous adsorption solubility;...
The sorption of water in polylactide (PLA) was measured at various vapor activities (0–0.85) and temperatures using a number experimental techniques, including quartz spring microbalance (QSM), crystal (QCM), situ time-resolved Fourier transform infrared-attenuated total reflectance (FTIR-ATR) spectroscopy. Additionally, prediction the isotherm PLA obtained with use nonequilibrium lattice fluid (NELF) model, where an excellent agreement between model data observed different (all below glass...
