Encyclopedia > Sabatier reaction

The Sabatier process involves the reaction of hydrogen with carbon dioxide at elevated temperatures and pressures in the presence of a nickel catalyst to produce methane and water. It is described by the following reaction: General Name, Symbol, Number Hydrogen, H, 1 Chemical series nonmetals Group, Period, Block 1 (IA), 1 , s Density, Hardness 0. ... Carbon dioxide is an atmospheric gas composed of one carbon and two oxygen atoms. ... General Name, Symbol, Number nickel, Ni, 28 Chemical series transition metals Group, Period, Block 10 , 4, d Density, Hardness 8908 kg/m³, 4. ... A catalyst (Greek: καταλύτης, catalytis) is a substance that accelerates the rate of a chemical reaction, at some temperature, but without itself being transformed or consumed by the reaction (see also catalysis). ... The simplest hydrocarbon, methane, is a gas with a chemical formula of CH4. ...

CO2 + 4H2 → CH4 + 2H2O

Discovered by the French chemist Paul Sabatier. A chemist is a scientist who specializes in chemistry. ... Paul Sabatier was born at Carcassonne in southern France on November 5, 1854. ...

Bosch reaction - Wikipedia, the free encyclopedia (151 words)
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]
Gilbert Canton - UF Journal of Undergraduate Research Paper (1782 words)
A non-linear relationship exists between the mass of the Sabatier reactor and the mass of fuel produced, and a linear relationship exists between the condenser mass and mass of fuel to be produced.
The methane and the water vapor produced by the reaction are passed through a condenser to separate the water from the methane.
The first is the analysis of the Sabatier reactor, and the second is the analysis of the condenser.
