Four Lump Kinetics Models to Describe the Aromatization Reactions of Liquefied Petroleum Gas

The aromatization reaction of liquefied petroleum gas has been studied by using three liquefied petroleum gases as raw material and LBO-A as catalyst, and four lump kinetics models networks have been put up on the basis of lump theory and the aromatization reaction mechanism. In the network the aromatization reaction species was firstly lumped into C4 , propylene, low molecule hydrocarbon, liquid and coke. A mathematical method was first introduced to study on the product distribution of liquefied petroleum gas aromatization reaction. The results from experimental data are in accordance with the quantitatively analytical conclusions drawn from the calculated data.
