This review considers and systematizes the results of studying the deactivation of hydrotreatment catalysts currently available in the scientific and technical literature. The effect the composition of the feedstock and the conditions of hydrotreatment have on the coking of catalysts is shown. The reasons for the morphological changes of the active component and the possibility of reducing this type of catalyst deactivation during commercial operation are considered. The effect of a pressure drop on the run time, the action of catalyst poisons, and the ways, in which they enters the hydrotreatment distillates is shown. This information could be useful and interesting to chemical engineers studying catalytic systems, and to workers of oil refining industry.
