synthesis of ammonia

The atmosphere is full of nitrogen gas, but it is unreactive and generally does not combine with other elements. But nitrogen has another application: it is the key ingredient in the explosive TNT (Trinitrotoluene). The Haber-Bosch industrial process for synthesis of ammonia (NH3) from hydrogen and nitrogen produces the millions of tons of ammonia gas annually needed to produce nitrates for fertilizers required to feed the earth’s growing populations. This process has been optimized extensively, but it still uses enormous amounts of … Synthesis of Ammonia The gas mixture is now cooled, compressed and fed into CO + 3H2= CH4 + H2O the ammonia synthesis loop.

The problems which need to be addressed further in order to scale-up the electrochemical synthesis of ammonia to the industrial level are examined. In the past two decades, several alternatives to the existing process have been proposed, including the electrochemical synthesis. Currently, ammonia is produced on a large scale throughout the world. In this strategy, activation of high-energy triple bonds of nitrogen is the most significant bottleneck, and is commonly considered as the rate-determining step of ammonia synthesis. Membranes. Exothermic reactions are, thermodynamically, less-favored at higher temperatures. Its primary industrial production is via the Haber-Bosch method; a process requiring high temperatures and pressures, and consuming large amounts of energy. Today, ammonia synthesis starts with generating hydrogen gas from fossil-fuel feedstocks. An ambient temperature, electrochemical synthesis of ammonia is an attractive alternative approach, but has, to date, not been achieved at high efficiency.
