Method to produce an oil from olefin-based resins by thermal degradation reactions

Abstract

Provided is a method for producing an oil comprising feeding an olefin-based resin into a reactor, converting the olefin-based resin into an oil by thermal degradation reaction, and recovering the produced oil, wherein the olefin-based resin is a low molecular weight (LMW) olefin-based resin. The LMW olefin-based resin comprises a molecular weight of less than 50,000 g/mol, preferably less than 40,000 g/mol measured according to ISO 16014-4. In an embodiment, method comprises a further step of cracking a higher molecular weight (HMW) olefin-based resin to produce the LMW olefin-based resin. Also provided are an oil produced according to the method and a use of the oil for as a feedstock for production of olefin-based resins. In the examples, a Hydrothermal liquefaction (HTL) process, which uses super-critical water as reaction media, is used for the thermal degradation reaction.
