Special Issue Information

Dear Colleagues,

Biomass is a renewable energy carrier that is considered to be environmentally advantageous. It does not contribute to global warming in the same way conventional fuels, such as coal, natural gas, or oil, do. Moreover, from the environmental point of view, the utilization of biomass can be even more attractive, when one considers processes such as gasification or pyrolysis. Biomass gasification is a rather mature technology that utilizes controlled process conditions involving heat, oxygen and/or steam to produce a high-hydrogen-content gas without complete combustion. Considering that growing biomass removes carbon dioxide from the atmosphere, the net emissions can be ultra-low, especially if coupled with carbon capture, its utilization, and storage. An emphasis will also be placed on biomass plasma gasification which is an active area of research and may bring substantial benefits to the quality of the gas product, but may also allow the utilization of more difficult fuels. The other key process, pyrolysis, which is considered as one of the most prevalent methods in biomass thermal conversion, allows three crucial components to be obtained: biochar, bio-oil, and pyrolysis gas. These components are increasingly being used in energy sectors and industry. Moreover, the knowledge regarding pyrolysis is crucial in gasification conditions, as devolatilization is only its sub-step. The Special Issue aims to present, disseminate, and standardize the most recent and innovative advances in biomass gasification, biomass plasma gasification, and biomass pyrolysis, focusing on theory, experimental research, and numerical research. Both research articles and reviews are welcome.

Willow is a promising biomass resource for addressing the challenges of securing stable domestic biomass fuels in Japan and utilising abandoned agricultural land. Among the willow species, Salix pet-susu Kimura KKD (known as ezonokinu willow, EW) stands out for its growth, high production, storage stability, production stability, and business stability. Previous studies have investigated fuel characterisation through gasification (co-gasification) of various biomass mixtures to enhance feedstock flexibility for gasifier commercialisation. However, the synergistic effects of co-gasification using fuels containing EW blended with Japanese cedar, a commonly planted forest species in Japan, remain unexplored. Therefore, this study explored CO2 co-gasification with different blend ratios of EW/cedar blended char and evaluated the fuel characteristics for each blend ratio to elucidate the synergistic effects. The prepared char samples were utilised in the CO2 gasification test with TG-DTA as the analyser. The results suggest that in the initial stages of the willow/cedar blended char co-gasification reaction, pore size and specific surface area significantly influence the reaction rate. Subsequent stages of the reaction are influenced by the promoting and inhibiting effects of inorganic components, which impact co-gasification. The synergy factor results for the willow/cedar blended char co-gasification suggest a reaction pathway. Full article
