Special Issue Information
Dear Colleagues,
Sorption-enhanced (SE) processes consist in equilibrium-limited reactions whose conversion is increased beyond equilibrium limits by subtracting from the reaction environment one of the gaseous byproducts. Such subtraction can be performed by means of a suitable solid sorbent or using a selective membrane. This local removal shifts the chemical equilibrium of the reaction (according to Le Chatelier’s principle), allowing up to 100% conversion to the desired product to be reached, despite the thermodynamic constraints.
In recent years, this class of processes has attracted increasing attention due to the appealing advantages attainable for equilibrium-limited reactions. Many novel SE processes have been proposed, while most of the attention has been devoted to:
- SE steam reforming of hydrocarbons;
- SE gasification of biomass;
- SE water–gas shift reaction;
- SE CO/CO2 hydrogenation.
SE processes can be performed in different types of reactors, such as fixed beds and membrane reactors, but fluidized bed reactors appear to provide some inherent advantages compared to the others. In fact, efficient heat management and easy solid particle circulation allow for safe steady operation and continuous sorbent regeneration in dual fluidized bed systems.
This Special Issue is focused on SE processes in fluidized bed systems. Papers dealing with the following topics are welcome:
- Experimental and modeling studies on new SE concepts;
- Studies on conventional SE concepts focused on novel aspects;
- Novel conventional or bi-functional sorbents for fluidized bed SE processes;
- Novel fluidized bed reactors for SE processes;
- Process, techno-economic and environmental performance analysis of SE processes.

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. Processes 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.
