Scholarcy highlights

  • Effect of operational parameters should be studied in both lab and industrial-scale
  • Greenhouse gases emitted from the excessive use of fossil fuels are threatening the environment, and alternative resources like biomass are being considered as a replacement
  • Biomass with high moisture content is better treated by hydrothermal carbonization method than any other process to generate biofuel
  • This paper aims to review the development of hydrothermal carbonization with a focus on the practical aspects of the process
  • After providing information about the biomass structure and general knowledge of hydrothermal carbonization, the challenges faced in attempts to improve the process have been identified as lack of valid kinetic and heat transfer models and insufficient data on continuous and large-scale reactors
  • Useful and practical suggestions have been presented to tackle all these challenges
