Process for Preparing Hydrotreating Catalyst

A process for preparing a hydrotreating catalyst which process comprises

• a) providing a first hydrotreating catalyst, comprising a group VI metal and a group VIII metal, selected from the group of fresh catalyst, regenerated catalyst, rejuvenated catalyst, fresh-, regenerated-, or rejuvenated catalyst fines, or mixtures thereof;
• b) milling the first hydrotreating catalyst to form catalyst fines unless the first hydrotreating catalyst already consists of fresh-, regenerated-, or rejuvenated catalyst fines or mixtures thereof;
• c) mixing the catalyst fines with at least a binding agent to form a mixture;
• wherein optionally the mixing and milling is at least partially combined and wherein optionally first hydrotreating catalyst consisting of fresh-, regenerated-, or rejuvenated catalyst fines are added after milling during mixing, wherein the mixture comprises at least 60 wt. % of catalyst fines based on the dry weight of the mixture;
• d) shaping the mixture to form a shaped mixture;
• e) heat treating the shaped mixture;
• f) contacting the heat-treated shaped mixture with a rejuvenating agent.
