| 摘要 |
In an industrial scale ammonia synthesis process (10, 110), in which the hydrogen necessary for such synthesis is obtained by subjecting natural gas (5) to partial oxidation (16), with an oxygen-rich gas (6) and in the presence of steam (2), obtaining a gaseous mixture (7) that comprises hydrogen, carbon dioxide, carbon monoxide and water, said gaseous mixture (7) is firstly subjected to catalytic conversion (18) to convert part of the carbon monoxide into carbon dioxide, then to decarbonation (20) to remove the carbon dioxide (20a) and finally to purification (22) to reduce the unconverted carbon monoxide concentration.
