Special Issue Information

Dear Colleagues,

The human society is facing a huge uncertainty relating global warming. One of the major contributors to this climate change is the anthropogenic emissions of excessive CO2. Hence, we urgently need appreciable strategies to reduce the emitted CO2, especially in the industrial fields, which account for more than half of the total emissions. In the past decade, CO2 capture and utilization (CCU) has rapidly developed into one of the most promising CO2 mitigation strategies. In the framework of CCU, CO2 can be directly obtained from industrial exhaust and air through the efficient CO2 capture and separation technologies, for instance, liquid absorption, solid adsorption, membrane separation, etc. Moreover, the obtained CO2 can be utilized as a carbon feedstock for value-added fuels and chemicals production via thermo-, photo-, electro- and plasma-catalysis, or their combination. Therefore, CCU enables not only large-scale CO2 emission reduction, but also a potential revenue of CO2 molecules within the human economic system.

This Special Issue aims to update the research progress of CCU technologies in support of their future developments. We kindly invite you to submit a contribution (in the form of research articles, reviews, letters and communications) to this Special Issue of Processes.

Contributions within the following topics are welcome, but not limited to them:

  • novel processes in CO2 capture and utilization;
  • advanced materials and technologies for CO2 adsorption and separation;
  • advanced catalysts and technologies for CO2 conversion;
  • novel theory and calculation methods in CO2 capture and utilization.

Four catalysts were prepared in our previous work using the solution combustion method, incipient-wetness impregnation method, colloid mill circulating impregnation method, and hydrothermal-precipitation method, respectively, labeled as SCM, IMP, T310, and HTP. And the performance (stability) of the four catalysts for CO2 reforming of CH4 was investigated at 800 °C. In this paper, the composition and structure characteristics of the deposited carbon on the above four catalysts were tested through TEM, Raman, TPH, and TG-DTG technologies. The results showed that filamentous carbon was the primary type of carbon deposition on the catalysts, and a large amount of accumulated carbon would block the catalyst pores, affecting the catalytic performance. The carbon deposited on the catalyst prepared using the hydrothermal-precipitation method calcined at 800 °C exhibited a high degree of graphitization, and the proportion of graphitized carbon was considerable, which is harmful to the stability of the catalyst. The decarburization temperature of the deposited carbon on the four catalysts was mainly in the range of 500–700 °C. Using the Coats–Redfern model, as the reaction order was set as 1, 2, 3, 4, and 5, the decarburization activation energy ranged between 50 and 80 kJ/mol. Full article

The inorganic-carbonate dual-phase membrane represents a class of dense membranes that are fabricated using diverse support materials, ranging from metals to ceramics. This dual-phase membrane consists of a porous metal or ceramic support with an introduced carbonate phase within the support pores. Compared with polymer and zeolite membranes, inorganic-carbonate dual-phase membranes exhibit exceptional CO2 selectivity at elevated temperatures (>500 °C), making them an ideal choice for high-temperature CO2 separation in power plant systems. The present paper provides a comprehensive overview of the separation principle, significant models, and preparation techniques employed in carbonate dual-phase membranes for CO2 separation. The present study aims to discuss key factors that limit the CO2 permeation performance and stability of membranes, while also exploring the potential applications of dual-phase membranes in various fields. The identification of key challenges in the future development of the carbonate dual-phase membrane has been highlighted in this work. The future trajectory of research and development should be directed toward overcoming these challenges, encompassing the synthesis technology of membranes, balance optimization of membrane structure and performance, modification of physical and chemical properties of molten carbonate, and advancement in high-temperature sealing techniques, as well as exploration of diverse membrane reactors based on carbonate dual-phase membranes for prospective applications.
