| 摘要 |
The present invention relates to a method for converting nitrogen (N2) into nitrate and/or ammonia comprising the steps of compressing air and separating nitrogen (N2) and oxygen (O2) therefrom, and either reacting earth alkaline metal with oxygen to produce earth alkaline metal oxide, using the high temperatures obtained to react N2 and O2 to NO, converting the NO with O2 to NO2, followed by the reaction of NO2 with water to result in HNO3 and NO; or reacting the nitrogen obtained with earth alkaline metal to produce earth alkaline metal nitride and reacting thereof with water to result in earth alkaline metal hydroxide and ammonia.
