what is bosch process with reaction?
Answers
The Haber process, also called the Haber–Bosch process, is an artificial nitrogen fixation process and is the main industrial procedure for the production of ammonia today. It is named after its inventors, the German chemists Fritz Haber and Carl Bosch, who developed it in the first decade of the 20th century.
The Bosch reaction is a chemical reactionbetween carbon dioxide and hydrogen that produces elemental carbon (graphite), water, and a 10% return of invested heat. It is named after the German chemist Carl Bosch
The Bosch reaction is a chemical reaction between carbon dioxideand hydrogen that produces elemental carbon (graphite), water, and a 10% return of invested heat. It is named after the German chemist Carl Bosch. This reaction requires the introduction of iron as a catalyst and requires a temperature level of 530-730 degrees Celsius.[1]
The overall reaction is as follows:
CO(g) + 2 H(g) → C(s) + 2 HO(g)
The above reaction is actually the result of two reactions. The first reaction, the reverse water gas shift reaction, is a fast one:
CO + H → CO + HO
The second reaction is the rate determining step:
CO + H → C + HO
The overall reaction produces 2.3×103 joules for every gram of carbon dioxide reacted at 650 °C. 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. Ruthenium also serves to speed up the reaction.
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.[2]
The reaction is also used to produce graphite for radiocarbon dating with Accelerator Mass Spectrometry.
The Bosch reaction is being investigated for use in maintaining space station life support. Though the Bosch reaction would present a completely closed hydrogen and oxygen cycle which only produces atomic carbon as waste, difficulties in maintaining its higher required temperature and properly handling carbon deposits mean that significantly more research will be required before a Bosch reactor can become a reality. One problem is that the production of elemental carbon tends to foul the catalyst's surface, which is detrimental to the reaction's efficiency.

Explanation:

n this process water gas (CO + H2, prepared from coal and water at 1270 K) is mixed with two times its volume of steam passed over catalyst Fe2O3, in the presence of promoter Cr2O3 or ThO2 at 773 K giving products CO2 and H2.
CO2 is dissolved in water under pressure (20 to 25 atm) and is removed leaving behind un dissolved h2
