Utilization of Carbon Oxides

Dear Colleagues,

Excessive carbon dioxide emissions are one of the major problems in today’s ecosystem. Carbon recycling is more vital than ever in order to control global warming and the consequent climate change. Fighting greenhouse gas emission and climate change has become one of the main challenges of the 21^st century. As a results, research on CO₂ capture and storage has attracted the attention of many researchers. However, besides the detrimental effect that excessive CO₂ emissions have, CO₂ is a cheap source of carbon, the efficient usage of which can ensure a secure sustainable economy. Therefore, recycling and utilization of CO₂ and its conversion to value-added chemicals can help us mitigate CO₂ and exploit this readily-available source of energy. Emissions of CO which mostly occur due to incomplete fuel burning in the diesel engines is another problem to consider. Currently, such problem is solved by full oxidation of CO to CO₂. However, CO is active chemical which, compared to CO₂, can be more easily converted into a variety of fuels and value-added chemicals. Methods of CO conversion to other chemicals such as methanol and higher alcohols have been well-established and well-studied. Therefore, there is a huge potential for conversion and utilization of the emitted COx which should not be overlooked. From the chemical engineering point of view, there are multiple ways to make use of such resources more efficiently. Our mission is to study these potential ways and to better optimize the current methods of COx utilization in order to have more sustainable energy resources.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. ChemEngineering is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
