Shock tube study on homogeneous thermal oxidation of methanol

摘要: Abstract Homogeneous thermal oxidation of methanoloxygen mixtures, highly diluted with argon, was studied in shock waves by following infrared emission various species during the course reaction. The equivalence ratio φ = 1.5 [CH 3 OH] [O 2 ] varied from 0.2 to 2.0. total density extended 1 × 10 −5 −4 mol/cm . For mixtures methanol and oxygen between 0.05 1.0%, expression describes induction period: r i 1.4 −16 [ CH >OH −0.1 O −O.19 Ar −O.62 X exp (201 kJ/mol /RT) s. very dilute experiments indicated a decrease power dependency argon density. In order obtain mechanism for methanol, profiles some were obtained numerical integration 57 reactions compared measured results. calculated periods agreed well ones. strongly influences period less than 1% OH since decomposition H plays an important role period.
