Kinetic Model of Desulfurization of Fluid Catalytic Cracking Gasoline by Extraction and Photochemistry

In the model system,the mechanism of desulfurization of fluid catalytic cracking gasoline by extraction and photochemistry was investigated, and kinetic equation is founded.The kinetics equation is: (-r_A)=-dc_Adt=0.435 2 c_A-462.28,Ea=16.9 kJ/mol,k_0=1.19.At the same time,the kinetic(equation) is validated by three types of FCC gasoline.The results indicate that the kinetic equation is adapted to the actual 1~# and 2~# FCC gasoline system.In the 2~# FCC gasoline,there is error between experiment and computation because of alkenes.
