| Abstract: | Pyrolysis of n-hexane was conducted in a plug-flow tube reactor at 923 K. The analytic results showed that the primary products consisted of C2-C4 paraffins, C2-C5 olefins, isohexanes, coke and H2. Based on the distribution of product types and selectivities, a chain mechanism of free radical reactions was established, and a quantitative analysis on the selectivities of various elementary reactions was carried out. |

| Keywords: | n-hexane pyrolysis free radicals chain reaction mechanism selectivity |
