Selected topics on the De novo synthesis of PCDD/PCDF on fly ash

摘要

Based on laboratory experiments with fly ash from municipal waste incinerators and model mix- tures, the main reactions for the denovosynthesis of PCDD/PCDF were identified. According to the results, particles of carbonaceous material from incomplete combustion were converted to a series of chlorinated aromatic compounds including PCDD/PCDF. In the process, two basic reactions were involved: a)the transfer of inorganic chloride to the macromolecular carbonaceous structure with formation of carbon-chlorine bonds, and b)the oxidative degradation of the structure.
