Desorption behavior of polycyclic aromatic hydrocarbons (PAHs) on various carbon black nanoparticles (CBNPs)

Worldwide carbon black nanoparticles (CBNPs) production is about 10 million tons per year. It is mainly used in rubber products, predominantly in tires and also as a pigment in printer ink, paints and plastics. CBNPs are produced by incomplete combustion of hydrocarbon fuels. Polycyclic aromatic hydrocarbons (PAHs) occur in the flame and are the precursor of hydrocarbon CBNPs. After synthesis the surface of CBNPs is covered with PAHs, some of which are known carcinogens. In this paper the desorption behavior of PAHs of different CBNPs are investigated. Therefore CBNPs were synthesized in a low pressure burner wi…
