| Abstract: | Free radical reaction network for steam cracking of n-butane,i-butane and mixed butane was established.The reaction kinetics parameters were optimized by means of quantum chemistry method.The entire free radical model for butane steam cracking was developed from view of integrating energy balance,material balance and momentum balance.This model can be used to predict composition of products and its distribution along the reactor tube when butanes are used as feedstock of steam cracking.The validity of the model had been confirmed by experiments of the bench-scale steam cracking. |
