Title:
METHOD FOR PRODUCING OLEFINS FROM POLYOLEFIN PLASTICS
Document Type and Number:
WIPO Patent Application WO/2019/203375
Kind Code:
A1
Abstract:
The present specification discloses a method for producing olefins from polyolefin plastics. The method for producing olefins from polyolefin plastics according to one aspect of the present invention heightens the vibration state of polyolefin molecules through a preliminary pyrolysis process in an auger reactor, thus maximally cleaves molecular chains at a secondary pyrolysis step in a main pyrolysis reactor, and, as a result, enables the high-yield production of ethylene and propylene.
