DEACT - Deactivating Catalyst in a CSTR

Solid catalysts can be conveniently studied in loop reactors, which allow measuring the rates by difference measurement across the catalyst bed. When operated continuously, they usually can be modelled as well-stirred tanks. Here the case of catalyst deactivation is studied. 

The batch balance for the catalyst with first-order deactivation is

Observe the influence of the catalyst decay constant, Kq on the outlet product concentration, which should slowly decrease. Make runs for a range of Kd values.
