Abstract
A catalyst of a water insoluble vanadyl sulfate or a complex catalyst, in which a specific oxide and a specific sulfate are combined to the water insoluble vanadyl sulfate are excellent not only in their activity, durability and SOresistance, not only in substantially no oxidization of SOto SOas in HCl resistant. Therefore, using this catalyst, a decomposition treatment of an organic halide(s) can be carried out with high efficiency and good stability. In particular, a efficient decomposition treatment of an organic halides(s) can be carried out also in the cases that dust is coexist; the gas to be treated contains SOor HCl; or they generate in the decomposition area.
