- Abstract
- A numerical model for the POX steam-oxygen conversion of methane to synthesis gas in a reversed flow non-premixed filtration combustion reactor with a reversed flow of steam-methane mixture and a continuous supply of oxygen to the reactor center is considered. The calculation was carried out for the oxygen/methane molar ratio 0.47 and steam/methane 0.5, i.e., in the parametric region close to the limit for the feasibility of the scheme. Various modes of initiation and control of flow reverse are considered, and dependences of the combustion temperature and the composition of products on the characteristics of the process are obtained. Comparison of the established cyclic mode of conversion with the predictions of the equilibrium model shows that kinetic constraints lead to a higher combustion temperature and incomplete conversion of methane. At high temperatures, the conversion proceeds via initial soot formation during the pyrolysis of methane and the subsequent reaction of soot with steam.
