摘要：
The thermal and hydrothermal processing of polyvinyl chloride waste was studied. The liquid product in the hydrothermal processing of polyvinyl chloride with 10% aqueous NaOH contains the least amount of chloroaromatic hydrocarbons in comparison with thermal processing without water. A scheme was proposed for two-step processing of polyvinyl chloride, in which the first step entails hydrothermal or thermal treatment followed by hydrodechlorination of the resultant liquid product on sulfide catalysts. Industrial sulfide and nanoheterogeneous NiWS and NiMoS catalysts synthesized by the authors were studied in the hydrodechlorination of the chlorine-containing mixtures. The greatest activity in the hydrodechlorination process was found for an unsupported NiWS catalyst synthesized ex situ.
