Pyrolysis

A more extensive way of obtaining virgin grade monomers for circular polymer production is chemical recycling through the combination Pyrolysis and Refinery.

The advantage of pyrolysis is that a wide range of rather unspecific waste mixtures can be converted. Additionally, it is the appropriate chemical recycling route for most polyolefines with uniform non-polar covalent bonds. The resulting products need to be upgraded, refined and reformed to close the cycle back to the virgin monomer.

Your Task

  • Carbohydrates from plastic waste

Our Solution

  • Continuous (catalyzed) Pyrolysis within LIST KneaderReactor without using solvents and Recovery of naphtha, diesel, aromatics or other hydrocarbons from high-viscous pyrolysis pitches
  • Compensation of low heat conductivity of polymers through large internal surface and intensive mixing
  • Eliminating the necessity for solvents by using Kneader intrinsic robust high-viscosity design which, in contrast, additionally introduces heat through dissipation.
  • Dosing and heating of the polymer and stoichiometric mixing of the catalysts
  • High separation efficiency and controlled residence time due to optimal interfacial renewal and plug-flow behavior
  • Fouling-free reactor design and trouble-free discharge of the residue
  • Evacuation of vapor products without product entrainment
  • Extensive testing facilities in our test centers in Switzerland and Korea, for targeted process development
  • Industrialization experience for scales up to 10 t/h polymer

Pyrolizer

  • interconnected gas headspace, large vapour cross sections
  • closed, safe design
  • large heated surface
  • optional vacuum design
  • robust all-phase design
  • viscous or solid discharge
