Predicting the catalyst operation life cycle is a crucial step of a new catalyst usage. The paper presents a method for assessment tests of the hydrodesulfuration catalyst by an accelerated deactivation. Results in a form of operational temperature trajectory of middle distillate hydrodesulfuration by Co-Mo sulfidic catalyst are presented.
