	Bosch reaction - Wikipedia, the free encyclopedia
		The Bosch reaction is a chemical reaction between carbon dioxide and hydrogen that produces elemental carbon (graphite), water and heat.
		Reaction temperatures are in the range of 450 to 600 °C. The reaction can be accelerated in the presence of an iron, cobalt or nickel catalyst.
		Together with the Sabatier reaction the Bosch reaction is studied as a way to remove carbon dioxide and to generate clean water aboard a space station [1]

	Haber process - Wikipedia, the free encyclopedia
		It was first used on an industrial scale by the Germans during World War I: Germany had previously imported saltpeter from Chile, but the demand for munitions and the uncertainty of this supply in the war prompted the adoption of the process.
		The reaction of nitrogen and hydrogen (1) is reversible, meaning the reaction can proceed in either the forward or the reverse direction depending on conditions.
		The forward reaction is exothermic, meaning it produces heat and is favored at low temperatures.

	Carl Bosch - Biography
		Bosch's opportunity for really large-scale work came when in 1908 the Badische Anilin- und Sodafabrik acquired the process of high-pressure synthesis of ammonia, which had been developed by Fritz Haber at the Technische Hochschule in Karlsruhe.
		Bosch was appointed Managing Director of the Badische Anilin- und Sodafabrik in 1919 and in 1925 was made Principal of the I.G. Farbenindustrie Aktiengesellschaft, which was created by the merger of the German coal-tar dye works.
		In 1935 Bosch was appointed Chairman of the Board of Directors of the I.G. Farbenindustrie A.G. Bosch was honoured in many ways and not only for his achievements and inventions in the field of industry, but also for his research in pure science, which he considered to be his duty.

		The method was translated into a large-scale process using a catalyst and high-pressure methods by Carl Bosch, an industrial chemist who won a Nobel Prize in 1931 jointly with Friedrich Bergius for high-pressure studies.
		A catalyst made mostly from iron enables the reaction to be carried out at a lower temperature than would otherwise be practicable, while the removal of ammonia from the batch as soon as it is formed ensures that an equilibrium
		The Haber-Bosch process is the most economical for the fixation of nitrogen and with modifications continues in use as one of the basic processes of the chemical industry in the world.

		Chemical equilibrium is the state in which a chemical reaction proceeds at the same rate as its reverse reaction; the rates of the forward and reverse reactions are equal, and the concentration of the reactants and products stop changing.
		In chemistry, an exothermic reaction is one that releases heat.
		Temperature is the physical property of a system which underlies the common notions of hot and cold; the material with the higher temperature is said to be hotter.

	Zmaczynski - Haber Process
		Fritz Haber and Karl Bosch of Germany developed the process in the early years of this century, before World War I. The effort was a joint one between German industry and the German University.
		While the reaction between nitrogen gas and hydrogen gas to produce ammonia gas had been known for many years, the yields were very small and the reaction very slow.
		Haber and Bosch and their coworkers determined the conditions necessary (high temperatures and very high pressures) and the catalysts necessary (a variety were found, the cheapest and most effective being oxides of iron with traces of oxides of other common elements).

		The activation energy of a reaction is the energy required by the reactants to achieve an intermediate state required before they form the products.
		Unfortunately experimentation showed that, as temperature approached the point at which the speed of the reaction was sufficient to produce a viable reaction the amount of ammonia produced was so low that the reaction was still unfeasible on as an industrial process.
		A catalyst is a substance that reduces the activation energy of a reaction, thus increasing the speed at which the reaction occurs, or in the case of equilibrium reactions the speed at which equilibrium is reached.

		Early in this century, a German academic chemist, Fritz Haber, and an industrial colleague, Carl Bosch, found that a mixture of Fe and Fe catalyzes this reaction at temperatures in the range of 400°C to 600°C. The yield of ammonia was further enhanced by working at gas pressures between 200 and 400 atmospheres.
		Therefore, high pressures drive the reaction forward, decreasing the number of moles of gas in the mixture.

		For more than 70 years, millions of tons of ammonia have been produced annually through the Haber-Bosch process; fertilizer made from this ammonia is estimated to be responsible for sustaining roughly 40% of the world's population and is the source for 40-60% of the nitrogen in the human body.
		Fritz Haber (1868-1934) and Carl Bosch (1874-1940) are credited with the discovery of the Haber-Bosch process for the synthesis of ammonia from its elements, a discovery that literally altered the course of 20th century history.
		In 1933, Bosch actually cautioned Hitler against the policy of dismissing non-Aryan scientists, pointing out to Hitler the severe damage which this policy threatened to inflict on the pursuit of chemistry and physics in Germany.

		Chemical reactions accompanied by an evolution of heat are called exothermic reactions.
		The heat of reaction is a difference between the intrinsic energy in the products of a chemical reaction and the intrinsic energy in the reactants, and it is either adsorbed or released during the course of the chemical reaction.
		Thus, if a chemical reaction takes place in stages, the algebraic sum of the amount of heat evolved in each separate stage is equal to the total amount of heat that would be evolved if the reaction took place in one stage.

		The reaction is reversible and exothermic, so that a high yield of ammonia is favoured by low temperature.
