Emission and Control of Air Pollution from Ships

Dear Colleagues,

Marine transportation is the main method of international cargo transportation owing to the advantages of large carrying capacity and low operating cost compared to other transportations. However, massive NO_x, PM, and SO_x emissions emitted from ships cause serious environmental pollutions in ports and coastal areas. Marine diesel engines emit approximately 20 million tonnes of NO_x, 10 million tonnes of SO_x, and 1 million tonnes of PM every year. Moreover, there is growing concern about greenhouse gas (GHG) emissions from ship engines. In addition, a methane slip problem exists in LNG powered ships. Thus, emission aftertreatment technologies are needed to control air pollutant emission from ships.

The aim of this Special Issue is to provide recent advances in the field of emission aftertreatment technologies. This topic encompasses selective catalytic reduction with NH₃ (NH₃-SCR) for removal of NO_x, catalytic combustion of CH₄, desulfurization systems and CO₂ capture and storage, etc. The topic is also highly relevant to novel materials for emission aftertreatment technologies, such as nanostructured catalysts and adsorbents.

Topics of interest for the Special Issue include but are not limited to:

• Selective catalytic reduction for removal of NO_x;
• Desulphurization;
• CO₂ capture and storage;
• Catalytic oxidation of CH₄ and VOCs;
• Removal of PM;
• Nanostructured materials for elimination of air pollutants.

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. Atmosphere is an international peer-reviewed open access monthly 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 2400 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.
