Pulsating light emission during the initiation of the low-temperature propane oxidation reaction due to the presence of quantum resonance in the system

Relevance. The study is relevant in the context of low-temperature oxidation of hydrocarbons, which is important for the development of new methods for controlling combustion reactions and improving the efficiency of fuel systems. Purpose. The aim of this work is to study the process of initiating the reaction of low-temperature oxidation of propane in a full-stirred reactor in a closed environment with intensive stirring. Methodology. The experimental method was used in this study. Results. During the experiment, a full stirred reactor was prepared, into which a mixture of propane and air was introduced in a ratio of 50:50 at a pressure of 100 Torr and a wall temperature of 600 K. During the experiment, the radiation of the reaction mixture was recorded. After 3.3 minutes with an interval of 18 seconds, two radiation peaks were observed, associated with the formation of ozone and weak shock waves due to water + negative halogen ion complexes near the reactor surface. The reactor was then evacuated by a forevacuum pump and then filled with air again under increasing pressure, and a periodic change in the reaction intensity caused by the desorption and combustion of intermediate products was recorded. Conclusions. Observations of radiation peaks associated with ozone formation and ion-molecular reactions provide valuable data on the mechanisms of initiation and progress of such processes. These results can be used to optimize combustion processes and improve the environmental performance of energy systems. The experimental results demonstrate important aspects of the mechanism of low-temperature propane oxidation, including the influence of ozone and ion-molecular reactions. They can help to develop effective combustion control technologies and reduce harmful greenhouse gas emissions into the atmosphere.
