Pyrolysis of carbazole: Experimental results and kinetic study

Carbazole pyrolysis was demonstrated 0.8-order, and associated Arrhenius parameters of [E (KJ/mol), A (s−1)] = [321.628, 1.832 × 1017] were determined. In comparison with dibenzothiophene, thermal stability of carbazole seems to be more unstable during thermal processing of residual oil. The present study may further improve our understanding of the evolution of complex ONCs in heavy oil refining.
