| 内容記述 | Dynamic behavior of the mild oxidation of propene by nitrous oxide over a platinum polycrystalline supported on silicagel with Dh=16％ of the platinum exposed, has been studied using an ordinary tubular flow reactor under atmospheric pressure. The reaction produces propanal as a partial oxidation product and carbon dioxide and water as complete oxidation products, in a parallel reaction at a temperature range of 290?320℃ and total flow rate range of 80?320 ml (NTP)/min. The rate of propanal formation exhibits a regular chemical oscillation at the specified gas composition and temperature regions whereas the rate of CO_2 formation shows a normal stable state through all the reaction conditions. The transient response of oscillating propanal caused by the stepwise change in gas composition is clearly characterized by the instantaneous oscillation responding rapidly to the new conditions, suggesting that a surface process controlling model may be accepted. The characteristic induction period of propanal formation is observed when the fresh catalyst surface is exposed to a reaction gas mixture, which results from the accumulation of some surface intermediates. This accumulation is necessary to start the oscillations. | |||||
