e-PCB - Catalytic co-pyrolysis of e-PCB and plastics using Zeolite

摘要

The present invention relates to a method of thermally decomposing an epoxy printed electronic circuit board (e-PCB), HDPE (high density polyethylene) or PP (polypropylene) simultaneously using HZSM-5 or HY zeolite catalyst, And recovering an oil that can be used as a raw material for a chemical reaction. The present invention provides a pyrolysis oil which greatly reduces the amount of brominated compound, which is a big problem in PCB decomposition, so that the pyrolysis oil can be practically used as a raw material for fuel or chemical reaction. Further, the present invention has an effect of controlling the amount or selectivity of phenol or BTX of the pyrolysis oil produced by selecting the pore size and the acidity of the catalyst.
