Patent

CA 2540286

The invention pertains to a process for activating an hydrotreating catalyst comprising a Group VIB metal oxide and a Group VIII metal oxide which process comprises contacting the catalyst with an acid and an organic additive which has a boiling point in the range of 80-500 ~C and a solubility in water of at least 5 grams per liter (20 ~C, atmospheric pressure), optionally followed by drying under such conditions that at least 50% of the additive is maintained in the catalyst. The hydrotreating catalyst may be a fresh hydrotreating catalyst or a used hydrotreating catalyst which has been regenerated.

Cette invention concerne un procédé d'activation d'un catalyseur d'hydrotraitement comprenant un oxyde de métal du groupe VIB et un oxyde de métal du groupe VIII, lequel procédé comprend une étape consistant à mettre le catalyseur en contact avec un acide et un additif organique qui présente un point d'ébullition compris entre 80 et 500 ·C et une solubilité dans l'eau d'au moins 5 grammes par litre (20 ·C, pression atmosphérique), laquelle étape est éventuellement suivie d'un séchage effectué dans des conditions telles qu'au moins 50 % de l'additif est conservé dans le catalyseur. Ce catalyseur d'hydrotraitement peut être un catalyseur d'hydrotraitement neuf ou un catalyseur d'hydrotraitement usagé qui a été régénéré.
