About this Research Topic
The development of efficient separation and purification technologies for the processing/treatment of complex gas streams is a challenging topic in environmental and chemical engineering, for the large number of possible applications. Among the currently existing technologies, adsorption has gained great consideration worldwide because of its easy operability, effectiveness and wide applicability. Although this process has been successfully applied at small scale as well as at large industrial level, the intrinsic complexity of adsorption phenomena in terms of gas composition, adopted sorbent and reactor configuration requires a tuned optimization of the operating parameters for the specific process.
One of the main challenges for the adsorption process intensification is the identification of configurations that are able to assure a selective adsorption of specific compounds, based on either new porous sorbents or innovative devices set-up, coupled with a thorough choice of the operating parameters. For many processes, in fact, more stringent regulatory or qualitative standard of the effluents/products are required every year, as the global technological and productive progress must adopt a sustainable vision for the future development.
This Research Topic is focused on high quality investigations regarding the use of porous sorbents for the selective adsorption/separation of gaseous compounds from gas mixtures. The studies should be focused on one or more of these aspects: equilibrium, kinetics, thermodynamics and/or mass and heat transfer, adsorbent-adsorbate interaction mechanisms, energy (also in terms of integration of renewable sources), desorption/reuse, reactors (e.g. fixed, fluidized and moving beds), porous materials, catalyst, etc. Lab-scale and pilot scale applications can be considered, as well as real cases applications or user-defined case-studies are welcomed, through both experimental or theoretical/simulation (also via computational fluid dynamics) works. The scope of the works can cover environmental or chemical engineering application fields such as exhaust or indoor gas treatment, biogas purification and upgrade to biomethane, hydrocarbon reforming, carbon dioxide capture and utilization, high-quality gas production, syn-gas refining, catalytic reaction, energetic applications, etc.
