Special Issue Information

Dear Colleagues,

In recent decades, non-renewable fossil fuels have been consumed constantly, their uses causing severe environmental pollution and forcing us to develop and valorize green renewable sources. Biomass represents organic renewable sources, including wood waste, agricultural waste, municipal solid waste, manufacturing waste, and landfill gas, and it can be converted into high value-added chemicals and liquid fuels. Many new technologies are quickly being developed and applied for the production of fuels and chemicals from different types of biomass or wastes. 

This Special Issue focuses on the valorization of organic solid wastes (mainly including waste tires, waste plastics, sewage sludge, algae, agriculture residues) into energy (hydrocarbon-rich liquid biofuel and gas biofuel) or high value-added materials (such as heteroatom-doped materials for electrochemistry utilization). We welcome original research on recent progress and new technologies in biomass conversion processes, from chemical catalysis to biocatalysis and bioprocessing.

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. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

The pyrolysis of pine sawdust was carried out in a fixed bed reactor heated from 30 °C to a maximum of 700 °C in atmospheric nitrogen and pressurized hydrogen (5 MPa). The yield, elemental composition, thermal stability, and composition of the two pyrolysis bio-oils were analyzed and compared. The result shows that the oxygen content of the bio-oil (17.16%) obtained under the hydrogen atmosphere was lower while the heating value (31.40 MJ/kg) was higher than those of bio-oil produced under nitrogen atmosphere. Compounds with a boiling point of less than 200 °C account for 63.21% in the bio-oil at pressurized hydrogen atmosphere, with a proportion 14.69% higher than that of bio-oil at nitrogen atmosphere. Furthermore, the hydrogenation promoted the formation of ethyl hexadecanoate (peak area percentage 19.1%) and ethyl octadecanoate (peak area percentage 15.42%) in the bio-oil. Overall, high pressure of hydrogen improved the bio-oil quality derived from the pyrolysis of pine biomass. Full article
