Abstract
|
Reports
kinetic characteristics of an in-situ crystallized FCC catalyst. Researchers
established a six-lump kinetic model containing 24 kinetic parameters, one
parameter for basic nitrogen poisoning, another parameter for aromatics
adsorption and other two parameters for catalyst deactivation. They estimated
kinetic parameters based on experimental data at 460, 480, 500 and 520 °С by
fourth order Runge–Kutta algorithm and the least square method. They
calculated frequency factors and apparent activation energies according to
Arrhenius equation. Predicted data of product distribution displayed good
agreement with experimental data.
Model analysis indicated that a relative low temperature was more suitable for the production of light oil. |
