Abstract
The invention pertains to a process for activating a hydrotreating catalyst comprising a Group VIII hydrogenation metal and a Group VI hydrogenation metal, which are substantially in the oxide form, on a carrier in which the hydrotreating catalyst is contacted with an additive which is at least one compound selected from the group of compounds comprising at least two hydroxyl groups and 2-10 carbon atoms, and the (poly)ethers of these compounds, after which the catalyst is dried under such conditions that at least 50% of the additive remains in the catalyst. The additive is preferably at least one compound selected from ethylene glycol, diethylene glycol, and polyethylene glycol, or a saccharide or a polysaccharide. The invention additionally pertains to the catalyst obtainable by this process, which shows high activity in hydrodesulphurization and hydrodenitrogenation reactions, and to the use of the catalyst in hydrotreating.
