摘要：
The present invention relates to a process for the catalytic reduction of nitrogen oxides contained in exhaust gases from combustions, which process comprises bringing said exhaust gases into contact with a Beta Zeolite exchanged with suitable amounts of cobalt salts, in the presence of a light hydrocarbon as the reducing agent. The present invention relates also to a catalyst for such a process, which catalyst comprises a Beta Zeolite exchanged with cobalt salts, characterized by a Co: zeolite Al molar ratio of
