Abstract: This paper introduces a new kind of method of nitrogen fixation in air for preparing HNO3 under the gentle conditions.Air and water were used as raw materials, NOx and steam of HNO3 were used as active reaction medium.The reaction temperature and pressure are 160~360℃, 0.02~0.4 MPa, respectively.The concentration of the new product NOx can reach 4~6 wt%.

Key words: Nitrogen fixation under gentle condition, Active reaction medium, Nitric acid
