Study of kinetic models for the pyrolysis reaction of propane

The pyrolysis reaction of propane was studied using a pulsed micro-reactor system with on-line chromatography, at 700–825°C and atmospheric pressure with chromatographically pure propane and high-purity nitrogen as reactant and diluent, respectively, at propane: nitrogen dilution ratios of 0.49, 0.9 and 1.9. A simplified kinetic model is presented. Marquardt's algorithm was used to estimate all the kinetic parameters in the model. The concentration of each species in the reaction system calculated using the model are close to the experimental values.
