Initial situation:

Surplus of C residues

Many carbon-containing residues are currently thermally recycled or landfilled. The material potential often remains unused due to a lack of economic processes for recycling the residues.

Examples of carbon sources:

• Waste plastics
• Carbon black

Shortage of C-nanomaterials

Carbon nanomaterials have extraordinary properties. Numerous fields of application are being researched and tested:

• Additive material in composites
• Functional component in lubricants or coatings

Objective

• Development of a novel process concept for the production of carbon nanomaterials.
• Upgrading of carbon-containing residues.

Work topics

• Dissolving and crystallising defined amounts of carbon with the aid of molten metals.
• Design and construction of an experimental plant for recrystallisation
• Determination of the optimal conditions for recrystallisation of carbon:
  • Selection of the melting alloy
  • Temperature control
  • Influence of the starting raw material
• Injection of the carbon-containing material
• Design of a process concept for the separation of the C-nanomaterial from the melt
• Investigation of the chemical composition and morphology of the C-nanomaterial obtained
