Microwave Pyrolysis of Plastics

Author: langfeng1 Time: 2018-03-14

Plastics cannot absorb microwave energy, as it has a very low dielectric loss factor. Therefore,

an absorbent must be mixed with the plastic to aid in heating the plastic in pyrolysis. Materials with high

dielectric loss factor are good candidates as an absorbents for plastic pyrolysis e.g. tyre shredded, silicon

carbide and carbon. The mechanism of plastic microwave pyrolysis is based on absorbing the microwave

energy via absorbent and subsequently transferring thermal heat to the plastic via conduction. The physical

properties and the volume ratio of the absorbent affects the uniformity of heating distribution.
