A new method of analysis to understand carbon combustion

Although it is the origin of the last industrial revolution and vastly studied for decades, the carbon combustion reaction still hides many mysteries. Particularly scientists encounter difficulties to understand the links between the temperature or the amount of oxygen used for the reaction, with its speed, what is usually called kinetics. This is of utmost importance, not only to better control the energy production possible with this reaction, but also in areas as broad as treatment of pollutants, fine particles or nanotechnologies. Researchers from the Paul Pascal Research Center, in Bordeaux just published in the journal Angewandte Chemie a new method of analysis they have developed, and which is based on the widely used thermogravimetric analysis (measurement of the mass loss as a function of temperature). This method, that they named successive isothermal steps (SIS), allows more precise and faster kinetic studies. Thanks to the efficiency of this new method, they have been able to explain why the carbon combustion reaction has stood up to researchers for more than 50 years. Furthermore, they have observed new behaviors for the reaction, that will serve as basis for future studies. Finally, the successive isothermal steps method is very general and should allow to study the kinetics of many other reactions still misunderstood today.
