An experimental and kinetic modeling study of the oxidation of acetone, both in the absence and the presence of NO, has been performed under flow reactor conditions in the temperature range of 700-1500 K and for different stoichiometries, ranging from fuel-rich to fuel-lean environments. The impact of stoichiometry on flow reactor data and ignition delay times has been studied, whereas the influence of NO has been analyzed under flow reactor conditions. A literature kinetic detailed model, slightly modified in the present work, has been used to simulate and explain the experimental findings.
and gasification processes.9,10 Sorbents that can be used include calcium acetate and calcium magnesium acetate, each of which emit acetone, which further reacts under combustion conditions.11 In addition, acetone may play an important role in the chemistry of the atmosphere, because it is one of the most abundant oxygenated organic compounds,12 produced either through the radical oxidation of hydrocarbons under atmospheric conditions13 or through uncontrolled burning fires.14 Despite the importance of understanding acetone oxidation, as well as its interaction with nitrogen oxides, previous work on its chemistry is not very extensive.
