Presentation topic: synthesis of ammonia by Haber -Bosch process Presented by MUHAMMAD SHEHZAD Presented To Dr. SHAFIQ UR REHMAN Department of Physics Agriculture University Faisalabad
Introduction ? Ammonia received its official name as ¡°Ammoniac¡± in 1787 from the Latin name of ¡°Ammonium chloride , Sal ammoniac¡± . ? Ammonia was first isolated by Joseph in 1774 and was termed by ¡°Alkaline air¡±. ? Haber Bosch process for produce ammonia from the Nitrogen in the air was developed by Fritz Haber and Carl Bosch in 1909.It was first use in industry in Germany during world war 1.
Manufacturing Process ? The synthesis gas for manufacture of ammonia is produce by steam reforming or partial oxidation of hydrocarbon feed. ? The various process used commercially in industries for production of ammonia are: 1) Imperial chemical industry(ICI) 2) Haber Bosch process 3) Braun purifier process
Haber Bosch proces ? The Haber Bosch process is the industrial implementation of the reaction of nitrogen gas and hydrogen gas . ? It is the main industrial procedure to produce ammonia ; ? N?+3H?¡ú2NH? ( ¦¤H= -92.4 Kg mol¡¥?)
Experimental Setup
Adsorption?Desorption
Conclusion ?Plasma-enhanced synthesis of ammonia using transition metal catalysts with a water electrode DBD reactor. ?All of the catalysts provided stable performances for at least 6 h, and Ni/Al2O3 maintained an efficient performance when recycled five times. ?there were no notable differences in the discharge characteristics for the three different metal catalysts, these results suggest that the catalytic effects provided by the chemistry of the catalyst surface are dominant over the physical effects of the catalysts in the plasma- catalytic synthesis of ammonia.
