Dear Colleagues,

The need to reduce the current dependence on fossil fuels has promoted the development of alternative sources for the production of fuels and chemicals. In this scenario, the valorization of biomass and waste is gaining increasing attention. Amongst the existing valorization routes, chemical approaches have the best perspectives for large-scale implementation. Pyrolysis is an efficient and eco-friendly process that makes it possible to produce fuels and chemicals from biomass and waste. The incorporation of suitable catalysts for pyrolysis is an interesting alternative to improve the selectivity and quality of key products. A wide range of catalysts have been proposed in the literature for biomass and waste valorization. Thus, the use of cracking catalysts—mainly of acid nature—represents a suitable option for the production of fuels and valuable chemicals such as BTX or light olefins. More recently, hydrogen production by combining pyrolysis and in-line catalytic steam reforming over metallic catalysts has demonstrated great potential. Moreover, from a technical point of view, different strategies have also been proposed as the use of the catalyst in a single step (in situ catalytic pyrolysis) or in two-step processes (thermal pyrolysis and the in-line catalytic transformation of pyrolysis volatiles). Therefore, this Special Issue aims to gather the most novel and relevant catalytic pyrolysis studies of different types of biomass and solid waste.

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. 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 2700 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.
