Special Issue Information

Dear Colleagues:

Biomass stands as an exemplary, sustainable feedstock with the potential to revolutionize the energy, biofuels, and materials sectors, steering us toward a greener society. The pursuit of efficient biomass treatment and utilization remains pivotal in bridging the gap between research endeavors and practical applications.

This Special Issue delves into the multifaceted realm of biomass conversion, exploring not only the intricate processes but also the diverse applications of the resultant products. Within this Special Issue, we extend a warm invitation for the submission of original research articles and reviews. We particularly encourage contributions that delve into various biomass conversion techniques, including pyrolysis, torrefaction, gasification, hydrothermal conversion, and biological conversion. The scope encompasses not only experimental investigations and applications but also modelling and simulation studies, encompassing process simulations, machine learning applications, life cycle assessments (LCA), and more.

Research areas may include (but not limited to) the following:

  • Innovative approaches to pyrolysis, torrefaction, gasification, hydrothermal, and biological conversion of biomass;
  • Pioneering catalysts and catalytic processes aimed at enhancing biomass conversion efficiency;
  • Strategies for enhancing and customizing the products derived from biomass;
  • Green products derived from biomass used for environmental applications;
  • In-depth kinetic and thermodynamic analyses of biomass conversion processes, uncovering the underlying mechanisms;
  • Machine learning models for a better understanding and utilization of biomass conversion processes;
  • Life cycle assessments and techno-economic analyses of emerging biomass conversion methodologies.

We look forward to receiving your contributions.

The stability of biocrude oil is a significant challenge for its storage, transportation, and refining. In this investigation, the thermal and oxidative stability of Spirulina-biocrude oil derived from a plug-flow continuous hydrothermal reactor was systematically studied. The biocrude oil was stored at three temperatures to simulate the winter (4 °C), spring and autumn (15 °C), and summer (35 °C) seasons, and in two atmospheres (air and N2) to simulate the conditions of a storage tank being sealed or kept open. Results demonstrated that the physicochemical properties of biocrude oil were highly influenced by the storage environment. The viscosity of biocrude oil increased with increasing storage temperature and time. The maximum viscosity (17,577 mPa·s) was observed when biocrude oil was stored at 35 °C and in an air condition over 84 days, 145% higher than fresh biocrude oil (7164.2 mPa·s). The viscosity increased by 10.9% when biocrude oil was sorted at 4 °C in an N2 atmosphere after being stored for 28 days. After long-term storage, biocrude oil still exhibited comparable characteristics to petroleum, with a slight decrease in HHV (31.36–33.97 MJ·kg−1) and the nitrogen-to-carbon ratio (0.087–0.092). This study indicated that the viscosity and HHV of the biocrude oil derived from a continuous reactor stored at 4 °C in an N2 atmosphere condition remained relatively unchanged, which enables the scheduling of oil refining production.
