Special Issue Information

Dear Colleagues,

Climate change and the increasing levels of greenhouse gas emissions, coupled with rapid urbanization and the depletion of exhaustible natural resources, are pressing global concerns. Addressing these challenges requires decisive action to meet resource demands while ensuring environmental protection, reducing emissions, and minimizing waste generation.

To achieve energy independence from fossil fuels and fulfill the European Union’s targets for renewable energy adoption and greenhouse gas reduction, significant advancements are necessary. The thermal processing of biomass and waste-derived fuels presents a promising solution to these needs.

Biomass has played a crucial role as a renewable energy source, contributing to lower or even negative CO2 emissions and increasing the share of renewables in global energy consumption. Additionally, refuse-derived fuel offers notable advantages when properly processed and utilized. However, compared to fossil fuels, the energy density of biomass and waste fuels remains relatively low, necessitating further research and technological improvements.

This Special Issue (second edition) aims to showcase recent advances in bioenergy production through biomass and waste conversion, encompassing pyrolysis, gasification, liquefaction, torrefaction, hydrothermal carbonization, direct combustion, and co-combustion. Furthermore, it highlights the utilization and valorization of by-products and residues from these processes in alignment with circular economy principles.

Topics of interest include, but are not limited to, the following:

  • Advanced methods for biomass and waste-to-energy conversion;
  • The optimization of pyrolysis, gasification, and liquefaction processes;
  • Innovations in torrefaction and hydrothermal carbonization;
  • Co-combustion strategies for enhanced energy recovery;
  • The utilization and valorization of process residues and by-products;
  • Environmental impact assessments and sustainability analyses;
  • Techno-economic evaluations of bioenergy systems;
  • Life cycle assessment and circular economy approaches.

We welcome original research articles, experimental and numerical studies, and comprehensive review papers summarizing the state of the art in these fields.

This study systematically investigates the effects of demineralization on the pyrolysis characteristics, kinetics, and thermodynamics of three biomass types (eucalyptus, straw, and miscanthus) using thermogravimetric analysis (TGA) combined with multiple kinetic approaches. The Coats–Redfern integral model was employed to determine the reaction mechanisms. The results indicate that the primary weight-loss temperature ranges for eucalyptus, straw, and miscanthus were 222.02~500.23 °C, 205.43~500.13 °C, and 202.30~490.52 °C, respectively. Demineralization increased the initial pyrolysis temperature and significantly enhanced the reaction rates. Kinetics analysis revealed that the ash content significantly influences the activation energy of the pyrolysis reaction. The average activation energies follow the trend eucalyptus (193.48 kJ/mol) < miscanthus (245.66 kJ/mol) < straw (290.13 kJ/mol). After demineralization, the activation energies of both straw and miscanthus pyrolysis decreased, with the largest reduction observed in straw, which dropped by 77.53 kJ/mol. However, the activation energy for eucalyptus pyrolysis increased by 12.52 kJ/mol after demineralization. The Coats–Redfern model and thermodynamic analysis demonstrated that each type of biomass followed distinct reaction mechanisms at different stages, which were altered after demineralization. Additionally, demineralization leads to higher ΔH and Gibbs free energy ΔG for eucalyptus, but lower values for straw and miscanthus, which indicate that the ash content has a significant impact on the biomass pyrolysis reaction. These findings provide fundamental insights into the role of ash in biomass pyrolysis kinetics and offer theoretical support for the design of pyrolysis reactors. Full article
