Ethane also inhibits the combustion of carbon monoxide, but less effectively than an equal amount of methane. - (Ms) (1./mm) (cm) (cm) 25% 50 % 100% 4.8 3*57 7 0.475 1010 1017 1021 3.4 A stoichiometric mixture of methane and air is burned in a flow reactor operating at constant temperature and pressure. Hydrogen also appears, and although its oxidation is retarded in the presence of methane, when the methane oxidizes the hydrogen goes 'in step' with it. The reaction proceeds via formaldehyde and carbon monoxide, and the further oxidation of the latter is apparently inhibited by the former or by its oxidation products. Methane combustion (see simulation at bottom of page) provides a significant fraction of the world's primary energy, and is used for home heating, cooking food, heating water, and electrical generation. Therefore, a higher catalyst temperature is necessary for the oxidation of methane, compared to longer chain hydrocarbons.

Increasing temperature provides particles with more kinetic energy, so the activation energy is more easily overcome.

The direct conversion of methane is attractive because the process is simple, but unfortunately its products are chemicals that are more reactive than methane. Catalytic experiments for complete methane combustion indicated a superior performance of samples containing Sc 2 O 3 compared to the CeO 2-ZrO 2 one in terms of reaction onset temperature, conversion values and activation energy.

Methane is the main hydrocarbon component of natural gas, which is a type of fossil fuel. ▸ For Pt catalyst, the reaction kinetics can be modelled using a first order reaction. This may take some time to load. [email protected], b The overall reaction orders of one and zero in methane and water concentration was found for stabilized steam-aged Pt catalyst in the presence and absence of water. Combustion of methane is a multiple step reaction summarized as follows: .
