By using Yanhua FCC gasoline and a selected fraction of Yanhua FCC gasoline as feedstocks, the effects of reaction temperature, Weight Hour Space Velocity (WHSV), and feedstock performance on yields of LPG, aromatics, and propylene production were investigated in a confined fluidized bed reactor. The experimental result shows that yields of aromatics, propylene, and aromatics + propylene for both Yanhua FCC gasoline and fraction of Yanhua FCC gasoline increase with the increase of reaction temperature at the same WHSV. Yields of aromatics, propylene, and aromatics + propylene decrease with the increase of WHSV at the same reaction temperature. Eight-lump kinetics and ten-lump kinetics are pointed out. The experimental results show that both kinetic models can predict the distribution of gasoline conversion and the composition of hydrocarbons of gasoline products under the different reaction conditions.
Key words: reaction condition; reaction kinetics; FCC gas‾ Yanhua; LPG.
