Kinetic Models for the Catalytic Cracking of Vacuum

The weight yields of gases lumped in C are calculated from 

The strong adsorption of the heavy aromatics Arj, is accounted for by multiplying the elements of K by a function 

To account for deactivation of the catalyst by basic nitrogen compounds, the rate coefficients are multiplied by the function 

Mobil s ten-lump model for catalytic cracking of gasoil. From Jacob et al. [1976], Weekman [1979], Froment [1986]. 

From this, a deactivation function with respect to the coke content can be determined
