Speciation data for fuel-rich methane oxy-combustion and reforming under prototypical partial oxidation conditions

摘要: Abstract Non-catalytic partial oxidation (POX) of hydrocarbon fuels is an important process for producing syngas. Quantitative experimental data under the demanding conditions relevant POX reactions, e.g. long residence times, rich stoichiometries and high temperatures, respectively, are rare in literature. Here, DLR high-temperature flow reactor setup was used to obtain a unique set validation reaction models general understanding fuel-rich chemistry. A systematic speciation methane with relevance oxidation/gasification processes presented. Both fast slow reforming reactions considered here. obtained temperature coupled molecular beam mass spectrometry (MBMS) detection. Five test case scenarios investigated, featuring ( ϕ =2.5) range from 1100–1800 K atmospheric conditions. CO, CO 2 acetylene two different amounts added system analysis addressing phenomena related oxidation. The new database includes quantitative species profiles major intermediate available as Supplemental material . compared results 0D modeling approach using GRI 3.0, USC-II, Chernov reduced model based on full mechanism. comparisons reveal significant differences predictions among themselves respect data, underlining this further mechanism development and/or optimization.
