Applications

Following the low temperature shift reaction and removal of carbon dioxide (CO2), the methanation reaction is used to remove any remaining carbon oxides from the process stream prior to ammonia synthesis. Trace amounts of carbon monoxide and carbon dioxide are reacted with hydrogen in the presence of a nickel oxide catalyst to produce a mixture of methane and water

CO + 3H2  →  CH 4+ H2O        H0 298  =-206.2KJ/mol

CO2 + 4H2  →  CH 4+ 2H2O      H0 298  =-165.0KJ/mol
