Special Issue "Thermochemical Biorefining"
Deadline for manuscript submissions: 15 January 2019
Prof. Lasse Rosendahl
Thermochemical biorefining holds enormous potential for sustainable production of carbonaceous chemicals and fuels; sustainable in terms of economic, environmental and resource efficiency. Within this scope, virtually all organic streams, be they wet/dry, virgin/residual, aquatic/terrestrial, flora/fauna-derived can be processed alone or in mixtures to intermediate platform chemicals and precursors, intermediate fuel products, such as syngas or bio-oils and, from there, efficiently converted to synthetic hydrocarbons or higher alcohols. However, challenges in implementation, process understanding, design and upscaling, identifying and alleviating bottlenecks in process flows, exist within all, as do significant challenges in establishing and documentating sustainability in its full meaning.
The scope of this Special Issue is to present the state-of-the-art within sustainable thermochemical biorefining for fuels and chemicals, and to highlight opportunities within sustainable processing realisable by these pathways.Prof. Lasse Rosendahl
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 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. Energies 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 1600 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.

Abstract: Hydrothermal liquefaction (HTL) of biomass is emerging as an effective technology to efficiently valorize different types of (wet) biomass feedstocks, ranging from lignocellulosics to algae and organic wastes. Significant research into HTL has been conducted in batch systems, which has provided a fundamental understanding of the different process conditions and the behavior of different biomass. The next step towards continuous plants, which are prerequisites for an industrial implementation of the process, has been significantly less explored. In order to facilitate a more focused future development, this review – based on the sources available in the open literature – intends to present the state of the art in the field of continuous HTL as well as to suggest means of interpretation of data from such plants. This contributes to a more holistic understanding of causes and effects, aiding next generation designs as well as pinpointing research focus. Additionally, the documented experiences in upgrading by catalytic hydrotreating are reported. The study reveals some interesting features in terms of energy densification versus yield of different classes of feedstocks, indicating that some global limitations exist irrespective of processing implementations. Finally, techno-economic considerations, observations and remarks for future studies are presented.
