The ammonia synthesis process is promoted by the catalytic reaction between hydrogen and nitrogen elements through the Haber process (Arora et al. 2018). It is performed in the as-designed reactor under operating conditions of 20–30 Mpa and 300–500 °C for pressure and temperature, ...
申请(专利权)人: AMMONIA CASALE S.A.发明人: FILIPPI Ermanno 摘要: In a process for producing ammonia (3) on the basis of a mixture (4) essentially comprising nitrogen and hydrogen obtained from natural gas (5), said natural gas (5) is subjected to a partial oxidation reaction with an ...
The nitride phase can be completely dissolved and removed during the subsequent melting process, which is necessary for downstream processing. Moreover, the other product of ammonia decomposition, nitrogen, can act as a heat carrier in a shaft furnace to maintain the reaction temperature and enhance...
