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.

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
