Contribution

It presents a comprehensive kinetic model with 600 reactions, validated against experimental data, for propane pyrolysis and pyrocarbon deposition.

Findings

Quantified 30 reaction products under various conditions.

Developed and validated a detailed kinetic model.

Integrated homogeneous and heterogeneous reaction mechanisms.

Abstract

High temeperature (900-1000\degree C) low pressure (<< 1 atm) pyrolysis of propane yields a pyrocarbon deposit, but also mainly hydrogen and hydrocarbons from methane to polyaromatics. 30 reaction products were exeperimentally quantified at different operating conditions. A detailed kinetic pyrolysis model (600 reactions) has been developed and validated based on the totality of experiments. This model includes a homogeneous model (describing the gas phase pyrolysis of propane) coupled with a heterogeneous model describing the pyrocarbon deposit.
