Effects of Reaction Condition on the Secondary Aromatization Reaction of Lanlian FCC Gasoline Products

By using Lanlian catalytic gasoline aromatization production as a feedstock, the effects of reaction conditions on the aromatization product yield, conversion, motor octane number (MON), research octane number (RON), and solvent product compound were researched in a confined fluidized bed reactor. The experimental results show that the changeable trend of secondary aromatization yield of Lanlian FCC gasoline are the same with FCC gasolines under the operation condition. Although the aromatics contents of FCC gasoline after the secondary aromatization are about 5%, MON value of production decreases and RON value of production remain no change and coke yield contents are very high. These show that the qualities of secondary aromatization of FCC gasoline are very poor.
