About this Research Topic
The constant growth of energy demand associated with the still significant dependency on fossil fuel reserves has been leading to a CO2 concentration rise in the atmosphere. Minimizing the environmental impacts caused by the emission of this major greenhouse gas has been a topic of several studies in the past decades. Carbon dioxide is also a known contaminant of gaseous fuels directly affecting the energy density. Carbon capture and purification technologies based on adsorption can be applied either as a strategy to mitigate CO2 emissions or to clean gas streams. Current challenges in the field include the development of new adsorbents that may selectively retain CO2 and process intensification via optimization of operating conditions. Recent developments of molecular simulation tools allied to experimental data obtained by carefully designed methods are also reported to contribute to the understanding and further enhancement of separation processes.
The goal of the research topic is to showcase how mainstream scientists on adsorption, separation processes, and material engineering have been addressing strategies to enhance CO2 separation and capture efficiency over different approaches and technologies. This Research Topic will focus on carbon capture and purification technologies based on adsorption - results of experimental and pilot studies, technology demonstrations, process design and optimization, molecular simulation and economic assessments, modeling relevant to technological and scientific progress.
Contributions on, but not limited to, the following topics are welcome:
• CO2 separation by adsorption (hydrogen, natural gas, flue gas)
• Multiscale screening of adsorbents for CO2 separation and capture
• Experimental methods to assess equilibrium and kinetics of CO2 adsorption
• Cyclic processes for CO2 separation (PSA, VPSA, TSA, ESA) or CO2 capture (integration of adsorption concept into capture technologies like CCS, CCU, CCC)
• Process modeling, equipment/reactor design, and simulation applied to CO2 adsorption
• Molecular simulation applied to CO2 adsorption
• Emerging technologies and applications
• Economical, environmental, management and safety issues related on CO2 capture by adsorption
