Abstract (en)

[origin: WO9834728A1] 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 DEG C to 150 DEG C.
