Abstract:

This paper reviewed the research progress in the influence of process conditions, including temperature, pressure, residence time, solvent type, and mass ratio of solvent to plastics, on the distribution of degraded products from the aspect of its degradation mechanisms by taking a widely used thermoplastic, polyethylene, as the example. In addition, the industrialization devices reported currently for solvothermal liquefaction degradation were introduced, and the future research direction was prospected.

Key words: polyethylene, solvothermal liquefaction, degradation
