Although the plunge in crude oil prices in recent years has caused a downfall in bio-diesel production, it had increased dramatically in different parts of the world, resulting in a large amount of glycerol as byproduct from the process. The increased amount of glycerol in the market had become a burden to the biodiesel producers who have limited options for managing this byproduct. Valorization of glycerol is thus needed to enhance the sustainability of the biodiesel industry.
Glycerol, the simplest tri-hydroxy alcohol has many potential applications. The multi-functionality of glycerol makes it a promising precursor for the production of high-value bio-renewable fuel/chemical products through various processes involving heterogeneous catalysis, e.g., esterification, etherification, oxidation, dehydration, acetalization, hydrogenolysis, chlorination and catalytic reforming. The glycerol-derived fuel/chemical products include liquid/gaseous fuels, fuel additives (e.g., solketal) and chemicals (e.g., glycerol mono-esters, glyceric acid, 1,3-dihydroxyacetone (DHA), epichlorohydrin, glycidol, tartronic acid, lactic acid, acrylonitrile, 1,2-propanediol and1,3-propanediol, etc.). The main challenge in catalytic conversion of glycerol in batch or continuous-flow processes is associated with deactivation of catalysts over time. Catalyst deactivation over time is the main issue in most reported processes for glycerol conversion. Thus, intense research is underway to develop catalysts of high activity and superb stability.
This Special Issue aims to cover recent progress and trends in conversion of glycerol into high-value bio-renewable fuel/chemical products through heterogeneous catalysis, including the designing, synthesizing, characterizing and evaluating heterogeneous catalysts for glycerol conversion.

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 papers will be 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. 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 1300 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.
