Course content

The need to reduce our dependency on non-renewable resources and switch to the utilization of renewable resources is increasing. Utilizing renewable energy and fuels dominate the public discourse, but renewable resources are and should be utilized as raw materials for chemicals and materials as well, both from a resource point of view and from a process economy point of view.

Plant biomass seems to be the renewable raw material which is available in the largest amounts on a global basis, but also organic waste material and animal-based biomass are used as raw materials in biomass-based processes. The composition and structure of biomass often precludes the use of some process engineering practices used in e.g. the petroleum industry. The course is intended to give an introduction to the challenges and opportunities of using renewable biomass as a raw material for industrial processes or as an energy source.

Course content

  • Engineering considerations for biomass-based process systems
  • Biofuels and biofuels production: Properties and process engineering
  • Biomass-based chemicals: Introduction, some typical manufacturing processes
  • Biomass-based materials: Properties and manufacturing processes

Topics taught

  • Properties of water; water management
  • VLEs of biomass-derived substances, azeotropes, phase separation, partial solubility
  • Rheological properties of biomass-based systems; mass and heat transfer
  • Biomass raw materials: Structure and chemistry
  • Biomass resources and their chemical composition
  • Common chemical reactions for biomass components
  • Mass and enthalpy balances for biomass-based processes
  • Typical unit operations employed in biomass-based processes
  • Solid, liquid and gaseous biofuels: Properties
  • Common processes for biofuel production
  • Some biomass-based chemicals and their manufacture
  • Biomass-based materials: Properties and production
