1. Hydrogen is mainly used for the production of ammonia via Haber process. 2. Ammonia produced by the Haber process is oxidized to nitric acid by the Ostwald process. 3. In the Haber process for the production of ammonia, hydrogen is generated from natural gas. 4. The ammonia required for this process is obtained by the Haber process from nitrogen and hydrogen. 5. Industrial facilities using the Haber process ( and its analogs ) have a significant ecology impact. 6. The largest-scale example is ammonia, which is prepared via the Haber process from nitrogen. 7. Germany had no such resources, so the Haber process proved essential to the German war effort. 8. The technical origins for CO-PrOx lies in the synthesis of ammonia ( Haber process ). 9. The first important man-made inorganic compound was ammonium nitrate for soil fertilization through the Haber process. 10. These reagents may sometimes be reused at the beginning of the process, such as in the Haber process.
