Self-heating characteristics of a hydroprocessing catalyst containing sulphided metal particles are reduced by coating the sulphided metal particles with a protective oxygen-containing layer by contacting the sulphided metal particles with an oxygen-containing composition at a temperature in the range of from -20 ~C to 150 ~C.
Pour réduire les caractéristiques d'auto-échauffement d'un catalyseur d'hydrotraitement contenant des particules métalliques sulfurées on recouvre les particules métalliques sulfurées d'une couche protectrice contenant de l'oxygène au moyen de la mise en contact des particules métalliques sulfurées avec une composition contenant de l'oxygène dans des conditions de température comprises entre -20 ·C et 150 ·C.
