Abstract
The present invention provides: a catalyst which has more excellent removability upon organohalogen compounds and is suitable for removing the organohalogen compounds from exhaust gases; and a process for removing organohalogen compounds with this catalyst. The catalyst for removing organohalogen compounds comprises titanium oxide (TiO2) and vanadium oxide as catalytic components, and has pores that includes a group of pores having a pore diameter distribution peak in the range of 0.01 to 0.05 μm and another group of pores having a pore diameter distribution peak in the range of 0.1 to 0.8 μm, and this catalyst is characterized by further comprising an oxide of at least one metal selected from the group consisting of manganese, cobalt, nickel, zinc, zirconium, niobium, molybdenum, tin, tantalum, lanthanum and cerium as another catalytic component. The process for removing organohalogen compounds involves the use of this catalyst.
