Perspectives in Catalytic Fast Pyrolysis, Catalytic Hydrodeoxygenation, and Catalytic Fast Hydropyrolysis

Dear Colleagues,

Biomass coming from lignocellulose (crops and forest residues) as well as municipal wastes is currently considered the most readily available alternative carbon source for advanced biofuel and raw chemicals production because of its abundance, low cost, and the fact that it does not compete with the food sector. Several processes have been developed to convert biomass into a liquid energy carrier, known as bio-oil, and fast pyrolysis is one of the most efficient and cost-effective alternatives. Pyrolysis bio-oil can be used for heating, electricity generation, and chemicals production. However, its direct use as transport fuel is limited as a consequence of its high content of water and oxygenated organic compounds (carboxylic acids, phenolic derivatives, aldehydes, sugars, lignin oligomers, etc.), which results in some undesirable properties, such as low heating value, high corrosivity and viscosity, and a significant tendency to polymerize during storage. For that, pyrolysis bio-oils should undergo an upgrading process to achieve transportation fuel specifications. In this context, catalytic fast pyrolysis, catalytic hydrodeoxygenation, and catalytic fast hydropyrolysis are considered the most promising technologies to obtain high quality products from biomass. With this background, the present Special Issue covers new advances of research in the described areas, including novel catalysts development, catalyst deactivation/regeneration studies, new upgrading chemistry and reactors design, large scale implementation, etc., and all manuscripts with outstanding results in this fields are welcome to be submitted.

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-anonymized 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.
