Abstract
The objectives are to elucidate homogeneous mechanisms of mercury oxidization and study the important factors on mercury oxidization in the homogeneous reaction system. The mercury oxidation experiments were conducted by injecting Hg gas with HCl or Cl_2 gas, using an electrically heated horizontal tube. Chemical equilibrium and chemical kinetics analyses were also carried out to study the main mercury elementary reaction scheme theoretically. The results show that HCI has little possibility of mercury oxidization. For Cl_2 addition, however, the mercury oxidization is enhanced more. The coexistence atmosphere of H_2O with Cl_2 affects promotion of mercury oxidization.
