- W2372180537 abstract "With external diffusion resistance eliminated,alkylation experiments were carried out over a solid acid catalyst in fixed-bed reactor,the fluid density in different conditions was calculated with four kinds of equations.An alkylation reaction kinetics model that related with alkylation reaction rate constant,catalyst deactivation rate constant and effective diffusion coefficient was deducted.The kinetic parameters,such as reaction rate constant,deactivation rate constant and effective diffusion coefficient,reaction activation energy,deactivation activation energy and diffusion activation energy,were determined through parametric estimation by using the alkylation experimental data,fluid density and catalyst density.The results showed that the kinetics model was highly credible under the condition of α=0.01 and well corresponded with reaction principle.The internal diffusion transfer of alkylation reaction occurred within middle range of diffusion resistance.The Lee-Kesler equation is the best model for calculating supercritical fluid density.With the increase of reaction temperature,alkylation reaction rate constant increased,effective diffusion coefficient reduced,catalyst deactivation rate constant decreased.When the reaction temperature was increased appropriately,it would be helped to improve the activity and stability of catalyst." @default.
