Microwave-metal Interaction Pyrolysis of Waste Polystyrene in a Copper Coil Reactor

摘要

Waste polystyrene was pyrolyzed into substituted aromatic compounds in a microwave oven using a copper coil reactor. The copper coil acts as an antenna and heat-generating object. The rate of reaction was found to be dependent on the size, shape, and form of the metal antenna. The pyrolysis products were found to contain 85% oily liquid, 10-12% gases, and char residue. The amount of gas was calculated by taking the difference. The liquid products were analyzed by using gas chromatography-mass spectrometry and found that it contains substituted benzene in addition to polycyclic aromatics and condensed ring aromatic compounds.
