For synthesis of ammonia

Most of the hydrogen for synthesis of ammonia is derived from oil or natural gas however, a number of cost-effective coal gasification installations have been commissioned in Asia, North America, and Eastern Europe where oil or natural gas is not available and where coal is abundant. 

Another important application of iron is as an industrial catalyst. It is used in catalyst compositions in the Haber process for synthesis of ammonia, and in Fischer-Tropsch process for producing synthetic gasoline. 

For synthesis of ammonia the effectiveness has been measured by Dyson and Simon [Ind. Eng. Chem. Ftmdam. 7,605-610 (1968)] and correlated by the equation...

Le Chatelier s principle /la-sha-tel-yayz/ If a system is at equilibrium and a change is made in the conditions, the equilibrium adjusts so as to oppose the change. The principle can be appfied to the effect of temperature and pressure on chemical reactions. A good example is the Haber process for synthesis of ammonia ... 

The other uses as catalysts are for synthesis of ammonia, methylation of carbon monoxide or carbon dioxide, steam reforming of naphtha and LPG, decomposition of peroxide, and treatment of waste water, etc. Market prices of precious metals are shown in Table 16.2 [3]. Ruthenium has a low price compared to a precious metal.
