Abstract

Abstract

To study the oxidative cracking process of tars during the combustion of syngas from MSW gasification, C₆H₆ was selected as the model compound, and the experiments of oxidation were carried out with and without Cl₂ in a homogeneous tubular flow reactor coupled with FT-IR. The oxidative products and oxidative degree as functions of temperature and ER were compared to reveal the effect of chlorine on C₆H₆ oxidation. The results indicate that chlorine has a clear excitation effect on C₆H₆ oxidation at low temperature. However, a further oxidation to CO₂ is inhibited by chlorine due to the increased OH consumption. Moreover, chlorine also promotes the polymerization reaction at high temperature and low equivalence ratio. Thus, the combustion of syngas from MSW gasification can proceed at lower temperature, while the environments with high temperature and low equivalence ratio should be avoided for the prevention of polymerization. Also, the chlorine content of MSW should be controlled to ensure the complete oxidation.
