Modeling the gas phase partial oxidations of hydrocarbons at moderate temperatures and increased pressures

摘要

The detailed kinetic C1-C2 scheme, suitable for the description of oxidation of hydrocarbons in a wide range of pressure and temperatures (P=1-100 atm, T=500-1500K) is considered. Feature of model is presence of the block of reactions of so-called peroxide cycle, without which account the correct description the oxidation stages at low temperatures is impossible. During calculations it is shown that the model well reproduces the cores known effects from experiments: delays of Melvin, inhibiting effect of oxygen and promoting effect of pressure. For the first time the effect of increase of selectivity of oxidizing conversion of superrich methane- air mixes at low temperatures and high pressures is found out.
