| Abstract;In the liquefaction of polyvinylchloride (PVC) and PVC contained polymer waste via dehydrochlorination pretreatment, new dehydrochlorination techniques and conversion of pyrolysis oil into light oil are employed. This paper chiefly introduces the dehydrochlorination techniques and conversion techniques to other chemical raw materials. To begin with, the decomposition behavior of PVC is described. Next, on the liquefaction of waste plastic, cracking liquefaction (for mixed plastic in non-industrial waste) and hydrogenation are described. On the gasification, low-temperature decomposition, high-temperature decomposition, and partial oxidation are explained. On the high-temperature and high-pressure water method, liquefaction with subcritical water, oxidation by oxygen in supercritical water, and conversion to carboxylic acid by liquid-phase oxidation method are described. |
