Control of reaction conditions, short residence times and completely inert surfaces are of major importance when studying aging mechanisms by soot formation. The use of ceramics as reactor material in combination with a special reactor design allows control over industrially relevant reaction conditions (T _max = 1100 °C, t _Residence = 50 ms) and sample shapes while avoiding interfering side reactions. We have successfully tested new ceramic kinetic reactors in two model systems of propane dehydrogenation and reactor coil material. The presented reactor setup allows long-term measurements with industrially relevant material samples under controlled conditions. In both model reactions it was possible to perform studies on regeneration methods by oxidation and to study the effects on the material using different in-situ and ex-situ techniques including 31 ^P MAS NMR measurements.
