摘要: Abstract A new method is proposed to determine the fluid catalytic cracking catalyst deactivation and kinetic parameters of a 6-lump model cracking, using few microactivity test (MAT) experiments. Instantaneous pressure drop outlet gas flow rate are recorded during test. The functions, related coke content, obtained these data, simple reactor model. These functions greatly depend on nature reaction temperature. This allows us adjust non-correlated function parameters.
