Abstract
The effect of catalyst macroporosity on deactivation rates under conditions of very rapid coke build-up was studied using a model feed in a trickle bed reactor. To accelerate coke formation, severe deactivation conditions were alternated with standard reaction conditions during which the catalyst activity remaining was determined. Hydrogenation and hydrodemetallation model compound reactions were used as measures of catalyst activity. The most macroporous catalysts generally accumulated higher coke loadings; however, they were able to retain their activity for a longer time period under identical conditions, as compared to the completely microporous catalysts.
