Popis:	The formation of condensed particles in atmospheric ethylene-oxygen and acetylene-air premixed flames catalyzed by the vapours of Fe(CO)5 and Mo(CO)6 was studied in the wide range of C/O ratio. Laser scattering and extinction measurements were carried out in a wide frame of flame conditions. The structure and the morphology of formed particles were analyzed using electron microscope. Different formation of the particles takes place due to the fuels and also to the catalyst. In the C2H2/air flame catalyzed with Mo(CO)6, particle formation starts at about threshold of soot formation (C/O ~ 0.6), while in the flames doped with Fe(CO)5, particle formation starts already in the lean range of both premixed flames investigated here.
