Abstract:

The previously developed mathematical model takes into account the activity of the catalyst. The influence of the activity of the catalyst on the rate of the reactions occurring during hydrotreating, the resulting rate constants of the deactivation. The adequacy of calculations of the improved model is checked. It was found that the reduction of catalyst activity by only 30% significantly affects the reaction rate constants, the reactions are slowed down by 18 times. The quality of the product is reduced when the catalyst is deactivated. To compensate for the loss of catalyst activity, it is necessary to vary the technological parameters, in particular, to increase the temperature in the reactor.
