The Production of Hydrogen Gas: Steam Methane Reforming

Steam from the furnace is mixed with natural gas, which contains methane to start the reaction. The steam-gas mixture enters the reformer from the inlet manifold. The reforming tubes are surrounded by burners, keeping the temperature of the mixture above 1,500 ⁰F. At these temperatures, methane (CH 4) reacts with steam (H 2 O) to produce hydrogen (H 2) and carbon monoxide (CO). The presence ...

The steam reforming of methane consists of three reversible reactions: the strongly endothermic reforming reactions (1) and (3), and the moderately exothermic water-gas shift reaction (2): CH 4 + H 2O DCO + 3H 2 DHº 298 = +206 kJ/mol (1) CO + H 2O DCO 2 + H 2 DHº 298 = -41 kJ/mol (2) CH 4 + 2H 2O DCO 2 + 4H 2 DHº 298 = +165 kJ/mol (3) It should be emphasized that CO 2 is not only produced ...

The decomposition of methane (Equation (8)) and the Boudouard reaction (Equation (9)) also occur and cause the catalyst activity of Ni to decrease; hence, the suppression of these side reactions and carbon deposition is one of the most significant problems for the development of practical Ni-based catalysts for the steam reforming of ethanol.
