摘要

对聚氯乙烯废料的热处理和水热处理进行了研究。与不加水的热处理相比，用 10%的 NaOH 水溶液对聚氯乙烯进行水热处理的液体产品中氯芳烃的含量最少。提出了一种分两步处理聚氯乙烯的方案，第一步是水热或热处理，然后在硫化物催化剂上对所得液态产品进行加氢脱氯。在含氯混合物的加氢脱氯过程中，对作者合成的工业硫化物和纳米异质 NiWS 和 NiMoS 催化剂进行了研究。发现原位合成的无支撑 NiWS 催化剂在加氢脱氯过程中活性最高。

Processing of Polyvinyl Chloride into Components of Fuel Fractions on Sulfide Catalysts

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.

期刊介绍： Chemistry and Technology of Fuels and Oils publishes reports on improvements in the processing of petroleum and natural gas and cracking and refining techniques for the production of high-quality fuels, oils, greases, specialty fluids, additives and synthetics. The journal includes timely articles on the demulsification, desalting, and desulfurizing of crude oil; new flow plans for refineries; platforming, isomerization, catalytic reforming, and alkylation processes for obtaining aromatic hydrocarbons and high-octane gasoline; methods of producing ethylene, acetylene, benzene, acids, alcohols, esters, and other compounds from petroleum, as well as hydrogen from natural gas and liquid products.
