Abstract

The present invention relates to a process for the preparation of nitrogen oxides (NO and NO.sub.2) by the reaction of nitrogen and oxygen in a plasma furnace. According to this process, a plasma of oxygen and nitrogen is introduced into the reaction chamber of the plasma furnace, whereof the internal surface of the walls is covered with a catalyst chosen from tungsten trioxide (WO.sub.3) and molybdenum trioxide (MoO.sub.3).
