✦ Synopsis

A reaction-deactivation model based on experimental observations was used to predict catalyst life for hydrotreating a solvent-refined coal oil. The model coordinates catalyst pore and pellet sizes to the quantity of carbonaceous material deposited. The results show that for a parallel fouling mechanism, a larger pore size and/or smaller pellet size catalyst tends to have a longer life as well as higher activity. The model also shows that deactivation due to coke deposition approaches a limit.
