The aromatization reaction of liquefied petroleum gas has been studied by using Huabei liquefied petroleum gas as the raw material and LBO-A as the catalyst. A four lump kinetics model, five lump kinetics model, and nine lump kinetics model network have been put forward on the basis of lumped theory and the aromatization reaction mechanism. In the network, the aromatization reaction species were first lumped into four parts, five parts, and nine parts. A mathematical method is first introduced to study the product distribution of liquefied petroleum gas aromatization reaction. The results from experimental data are in accordance with the quantitative analytical conclusions drawn from the calculated data.
