High-Temperature Carbon Particle Formation and Decay in Carbon Suboxide Pyrolysis behind Shock Waves

The formation of carbon particles following the pyrolysis of C₃O₂ was investigated behind reflected shock waves towards high temperatures. It is known that in hydrocarbon pyrolysis the temperature range for soot formation extends from about 1300 K to 2200 K. That holds also for C₃O₂. Here it could be observed that particle formation starts again above 2300 K and increases towards a maximum at around 3000 K, falling off steeply above 3450 K. This maximum is nearly as high as that of the low ''temperature particle yield curve'' [1] at around 1600 K.
