Abstract
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.
