The water–gas shift reaction (WGSR) describes the reaction of carbon monoxide and water vapor to form carbon dioxide and hydrogen: CO + H 2 O ⇌ CO 2 + H 2. The water gas shift reaction was discovered by Italian physicist Felice Fontana in 1780. It was not until much later that the industrial value of this reaction was realized.
The water gas shift reaction is the reaction between carbon monoxide and steam to form hydrogen and carbon dioxide: CO + H 2 O ⇌ CO 2 + H 2. This reaction was discovered by Felice Fontana and nowadays is adopted in a wide range of industrial applications, such as in the production process of ammonia, hydrocarbons, methanol, hydrogen and other chemicals.
The Bosch reaction is a catalytic chemical reaction between carbon dioxide (CO 2) and hydrogen (H 2) that produces elemental carbon (C,graphite), water, and a 10% return of invested heat. CO 2 is usually reduced by H 2 to carbon in presence of a catalyst (e.g. iron (Fe)) and requires a temperature level of 530–730 °C (986–1,346 °F).
Water-gas-shift reaction. The reaction that occurs in a water-gas-shift reactor is CO + H 2 O CO 2 + H 2. This produces a syngas with a higher composition of hydrogen fuel which is more efficient for burning later in combustion. Physical separation process.
Another issue with dry reforming is situated in the fact that it operates at conditions that produces water. As a result, this water can lead to unwanted back-reaction to CO 2 via the water-gas shift reaction. To prevent CO 2 from being formed, and consequently losses in CO yield, CO 2 can be adsorbed onto calcium oxide.
Hydrocarbonate is an archaic term for water gas composed of carbon monoxide and hydrogen generated by passing steam through glowing coke.Hydrocarbonate was classified as a factitious air and explored for therapeutic properties by some eighteenth-century physicians, including Thomas Beddoes and James Watt.

Most important is the water-gas shift reaction, which provides a source of hydrogen at the expense of carbon monoxide: [8] H 2 O + CO H 2 + CO 2 {\displaystyle {\ce {H2O + CO -> H2 + CO2}}} For FT plants that use methane as the feedstock , another important reaction is dry reforming , which converts the methane into CO and H 2 :
