ABSTRACT:
The present invention provides a catalyst having excellent capability of removing organic halogen compounds such as dioxins, a method for preparing the catalyst, and a method for removing organic halogen compounds using the catalyst. A catalyst for removing organic halogen compounds comprises titanium oxide as a catalyst component and has pores including a group of pores having a pore diameter distribution peak in a range of 0.01 to 0.05 gm and another group of pores having a pore diameter distribution peak in a range of 0.1 to 0.8 .mu.m. Another catalyst for removing organic halogen compounds comprises titanium oxide and a titanium-silicon composite oxide as catalyst components and has pores including a group of pores having a pore diameter distribution peak in a range of 0.01 to 0.05 .mu.m and another group of pores having a pore diameter distribution peak in a range of 0.8 to 4 .mu.m.
