CATALYST FOR COMBUSTION EXHAUST GAS PURIFICATION AND DENITRATION PURIFICATION METHOD USING THIS CATALYST

摘要

The present invention provides a denitration catalyst which has long-term durability. The present invention is a catalyst for denitration purification of a combustion exhaust gas at 300°C or less, which is a catalyst obtained by having an MFI zeolite support Co and treated with silane. The present invention is a method for denitration purifying a combustion exhaust gas at 300°C or less, which comprises a step wherein a combustion exhaust gas is brought into contact with a catalyst in the presence of an alcohol that serves as a reducing agent, and wherein the catalyst is one obtained by having an MFI zeolite support Co and treated with silane.
