Abstract: The present invention concerns the use of a catalyst comprising an extruded essentially alumina-based support, constituted by a plurality of juxtaposed agglomerates and partially in the form of packs of flakes and partially in the form of needles, and optionally comprising at least one catalytic metal or a compound of a catalytic metal from group VIB and/or at least one catalytic metal or compound of a catalytic metal from group VIII, further comprising at least one dopant selected from the group formed by boron, phosphorous, silicon (or a silica different from that which can be found in the support) and halogens, in an ebullating bed process and for hydrorefining and hydroconverting hydrocarbon feeds.

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.
