Аннотация:—The review deals with the hydrolysis of polyvinyl chloride waste in media of alkalis and organic basesand with the treatment of chlorine-containing waste in critical media (water, ammonia, methanol, carbon dioxide).The principles and mechanisms of the hydrodechlorination and hydroconversion of polyvinyl chloride/vacuumgas oil mixtures and of the gasifi cation of polyvinyl chloride waste and municipal chlorinated plastic waste aredescribed. Procedures for joint hydrothermal treatment and gasifi cation of polyvinyl chloride waste with biomassand coal and various specifi c methods for polyvinyl chloride dechlorination are analyzed. The major advantageof hydrothermal treatment of polyvinyl chloride in subcritical water is that the products contain no chlorinatedorganic compounds. The major advantages of the dehydrochlorination of waste containing polyvinyl chloride arehigh degree of removal of organic chlorine and high H/C ratio in recycled products.
