METHOD AND DEVICE FOR PRODUCING WASTE PLASTIC PYROLYSIS OIL WITH REDUCED CHLORINE

Document Type and Number:

WIPO Patent Application WO/2023/195710

Kind Code:

A1

Abstract:

The present disclosure provides a method for producing waste plastic pyrolysis oil with reduced chlorine, the method including: a first step of charging a waste plastic feedstock and modified red mud into a reactor; and a second step of pyrolyzing the waste plastic feedstock in the reactor and recovering pyrolysis oil, wherein when the modified red mud is subjected to X-ray diffraction (XRD) analysis, an intensity of a first peak at a 2θ diffraction angle of 14 ± 0.1 ° is higher than an intensity of a second peak at a 2θ diffraction angle of 14.5 ± 0.1 °.
