Verkkoberreni and wang (2011) studied the dynamic modeling, simulation and optimization of thermal cracking of propane in a tubular reactor by employing. Verkkowith the increasing demand of propylene market, the traditional processes have been unable to meet the demand of propylene market (r. Hu et al. ,. Verkkoin this paper, using a suitable model for propane thermal cracking and based on a cost function, the optimal temperature profile is obtained.
