The aromatization reactions of FCC gasoline and C4 LPG have been studied by using three FCC gasolines and three C4 LPGs as raw material and LBO-A as a catalyst. The aromatization processing functions of FCC gasoline and FCC gasoline have thus been put forward. The relative coefficient and relative impact of F-FCC and F-C4 and aromatics production yield of Lanlian FCC gasoline and Huabei C4 LPG are contrasted. The absolute average deviation and the relative average deviation are very low. Thus, the equations qualify for the aromatization reaction of FCC gasoline and C4 LPG.
