Carbon black formation from the mixture of acetylene and benzene
- All-Russian Research Institute of Natural Gases and Gas Technologies, Moscow (Russian Federation)
Formation of carbon black during isothermal pyrolysis of acetylene, benzene, and their mixtures was studied at 1200{degrees}C. Induction times of carbon black formation from acetylene, benzene, and their mixture were measured. The specific surface area of the carbon black obtained by pyrolysis of acetylene and benzene was nearly the same (21.0 m{sup 2}/g). Pyrolysis of acetylene-benzene mixtures resulted in carbon black with a much lower specific surface area (7.0 - 10.0 m{sup 2}/g); the particles of carbon black were shown to be formed by acetylene decomposition, while benzene was consumed but for the growth of particles. The observed inhibition of the particle formation from benzene is accounted for by the difference in the induction times during carbon black formation.
