Special Issue Information

Dear Colleagues,

The demand for hydrogen in key sectors, such as ammonia production, oil refining and methanol production, is expected to grow over the coming decades. Moreover, 96% of the global hydrogen produced is of fossil origin, i.e., the main sources are the reforming of natural gas and oil fractions, and coal gasification. The processes for producing hydrogen from biomass and waste are therefore attracting increasingly more attention, with thermochemical routes being those with the best perspectives for their full-scale development. The catalytic steam reforming of biomass and waste-derived products provides an opportunity for producing hydrogen from renewable and sustainable sources. Two types of processes may be considered as direct and indirect routes. On the one hand, direct routes pursue the conversion of biomass and waste into hydrogen in an integrated process, with pyrolysis and in-line reforming being the ones most representative of this strategy. On the other hand, in the indirect approach, an intermediate product (bio-oil) is produced and transported to centralized units for its reforming. Despite the research conducted on these processes in recent years, the studies published are clearly of a preliminary nature, and further research is required for their scaling-up. It should be noted that key aspects of the catalytic reforming step remain unclear, such as the optimization of the reforming catalysts, knowledge of catalyst deactivation, and reactor design and modeling.

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 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.

The performance of a Ni commercial catalyst has been studied under reaction-regeneration cycles in a continuous process consisting of the flash pyrolysis (500 °C) of high-density polyethylene (HDPE) in a conical spouted bed reactor (CSBR), followed by catalytic steam reforming in-line (700 ºC) of the volatiles formed in a fluidized bed reactor. The catalyst is regenerated between reactions by coke combustion in situ in the reforming reactor, using a sequence of air concentrations and following a temperature ramp between 600 and 700 °C. Several analytical techniques (TPO, TEM, XRD, and TPR) have proven that the catalyst does not fully recover its initial activity by coke combustion due to the sintering of Ni0 active sites. This sintering process is steadily attenuated in the successive reaction-regeneration cycles and the catalyst approaches a steady state. Full article
