Abstract :
In order to avoid dioxin emission from municipal solid waste combustion (MSW), chemical looping combustion was considered. The interaction between HCl and Fe2O3 was studied in this paper and experiments were carried out in a fixed bed reactor. Chlorine was measured by methyl orange spectrophotometric method. The intermediate reactions were calculated with standard Gibbs free energy and reaction equilibrium constants. The result showed that: when Fe2O3 is used as oxygen carrier, the conversion of HCl to chlorine can be suppressed, thus reduce Dioxin emission.
