Catalyst Deactivation in Hydrocarbon Processing

Dear Colleagues,

The loss of catalytic activity and/or selectivity over time is an issue of tremendous importance for heterogeneous industrial catalytic processes. The degree of catalyst deactivation depends mainly on the properties of the feed and operating conditions, and it is caused by a variety of mechanisms, such as poisoning, fouling (carbon deposition), thermal degradation, vapor formation, and attrition/crushing. As the performance of catalysts decreases with time, periodic increases of reaction temperature are required in order to maintain constant product yields and/or quality, which means that costs to industry for catalyst replacement and process shutdown are in the order of billions of dollars per year. While catalyst deactivation is inevitable, some of its immediate, drastic consequences may be avoided, postponed, or even reversed.

This Special Issue aims to draw together scientific works on the recent advances in catalyst deactivation, catalyst regeneration, novel catalyst formulations with enhanced stability/tolerance characteristics, understanding of mechanisms, advances in process line-ups, advances in process conditions and reactors, and development of improved methods and tools for investigation.

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 250 words) can be sent to the Editorial Office for assessment.

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. Catalysts 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 2200 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.
