Special Issue Information

Dear Colleagues,

This is a call for papers from the journal Processes on a Special Issue on "Recent Advances in Carbon Dioxide Capture and Utilization". It will feature original research, application papers, and review papers. Topics include but are not limited to emerging policies on carbon dioxide mitigation, carbon dioxide control technologies, carbon dioxide capture, purification and reuse technologies, and carbon dioxide bio-fixation technologies.

The keywords related to these topics are as follows: 

  • Emerging policies on carbon dioxide mitigation: carbon footprint label, carbon tax, life cycle assessment on carbon dioxide emissions, and circular economy on carbon dioxide;
  • Carbon dioxide control technologies: chemical/physical technologies on carbon dioxide elimination, process design for carbon dioxide reduction;
  • Carbon dioxide capture, purification and reuse technologies: carbon dioxide capture technologies, carbon dioxide purification technologies, carbon dioxide circular technologies;
  • Carbon dioxide bio-fixation technologies: carbon dioxide bio-fixation by plants, carbon dioxide bio-fixation by microorganisms.

The accepted papers of this Special Issue of Processes will be published by MDPI, in open access. Each submission to this Special Issue should contain new material, e.g., in the form of technical extensions, more in-depth evaluations, or additional use cases. These submissions will undergo a peer-review process according to the journal’s rules of action. At least two technical committees will act as reviewers for each article submitted to this Special Issue; if needed, additional external reviewers will be invited to guarantee a high-quality reviewing process.

We look forward to your submissions.

Sincerely yours,

Prof. Dr. Hsin Chu

This paper focuses on the best way to produce methanol by Coke Oven Gas (COG) conversion and by carbon dioxide capture. The COG, produced in steelworks and coking plants, is an interesting source of hydrogen that can be used to hydrogenate carbon dioxide, recovered from flue gases, into methanol. The architecture of the reuse process is developed and the different process units are compared by considering a hierarchical decomposition. Two case studies are selected, process units are modelled, and flowsheets are simulated using computer-aided design software. A factorial techno-economic analysis is performed together with a preliminary carbon balance to evaluate the economic reliability and the environmental sustainability of the proposed solutions. The production costs of methanol are equal to 228 and 268 €/ton for process configurations involving, respectively, a combined methane reforming of COG and a direct COG separation to recover hydrogen. This cost is slightly higher than the current price of methanol on the market (about 204 €/ton for a process located in the USA in 2013). Besides, the second case study shows an interesting reduction of the carbon footprint with respect to reference scenarios. The carbon dioxide capture from flue gases together with COG utilization can lead to a competitive and sustainable methanol production process depending partly on a carbon tax. Full article

Protic ionic liquids have been regarded as promising materials to capture CO2, because they can be easily synthesized with an attractive capacity. In this work, we studied the CO2 absorption mechanism by protic ionic liquids (ILs) composed of diamino protic cations and azolide anions. Results of 1H nuclear magnetic resonance (NMR), 13C NMR, 2-D NMR and fourier-transform infrared (FTIR) spectroscopy tests indicated that CO2 reacted with the cations rather than with the anions. The possible reaction pathway between CO2 and azolide-based protic ILs is proposed, in which CO2 reacts with the primary amine group generated from the deprotonation of the cation by the azolide anion.
