Selective Catalytic Reduction of NOx from diesel engine exhaust using injection of urea

Process for treating nitrogen oxide-containing gas using a cerium zeolite

The invention relates to a process for treating nitrogen oxide-containing gas substantially having a temperature in the range of 300-560 DEG C, for instance exhaust gases of gas engines or off-gases of power plants, in which the gas is passed over a cerium-containing zeolite catalyst in the presence of substantially an excess of a NH-containing...
