- The Bosch process is a chemical process used to produce hydrogen gas and carbon dioxide by reacting carbon monoxide and steam over an iron or cobalt catalyst. The process is named after its inventor, German chemist Carl Bosch. It is an important industrial process used in the production of ammonia and other chemicals.
- The Bosch process is a method for producing hydrogen gas by reacting steam with hot carbon. The hydrogen gas is then reacted with nitrogen gas to produce ammonia via the Haber process. The overall reaction is:
- N2 + 3H2 –> 2NH3
- The hydrogen gas produced by the Bosch process is one of the reactants for the Haber process to produce ammonia.
- HABER-BOSCH PROCESS FOR AMMONIA: The processcombines nitrogen from the air with hydrogen derived mainly from natural gas (methane) into ammonia.
- Various steps are involved in Bosch process. It is given as follows:
- Production of water gas: The mixture of carbon monoxide (CO) and hydrogen (H2) is obtained by passing superheated steam over red hot coke or coal at 1000C. This process of formation of water gas from coke or coal is called coal gasification.
- Reduction of steam by water gas: To remove CO and to increase the production of hydrogen gas from water gas CO is oxidized to CO2 by mixing it with more steam at 673K in the presence of iron chromate and little chromium oxide as catalyst. The reaction in which carbon monoxide of water gas reacts with steam to give carbon dioxide and more hydrogen gas is called the water gas shift reaction.
