    Abstract: The present invention pertains to a process for activating a catalyst composition comprising at least one hydrogenation metal component of Group VI and/or Group VIII of the Periodic Table, and an S-containing organic additive, wherein the catalyst is contacted with hydrogen at a temperature between room temperature and 600 DEG C, preferably 100-450 DEG C, characterised in that prior to or during the contacting with hydrogen the catalyst is contacted with an organic liquid. Preferably, the contacting with the organic liquid is carried out prior to the contacting with hydrogen. The organic liquid may be a hydrocarbon with a boiling range of 150-500 DEG C, preferably white oil, gasoline, diesel, or gas oil or mineral lube oil. It was found that the application of an organic liquid prior to or during the hydrogen treatment results in catalysts with an increased activity.

    Abstract: The present invention pertains to a process for sulphiding a catalyst composition comprising at least one hydrogenation metal component of Group VI and/or Group VIII of the Period Table, and an organic additive wherein the catalyst composition is first contacted with an organic liquid, followed by the catalyst being contacted with hydrogen and a sulphur-containing compound in the gaseous phase, wherein less than 40 %, preferably less than 35 %, more preferably less than 25 %, most preferably less than 15 %, of the sulphur present in the sulphided catalyst is added with the organic liquid. The process of the present invention makes it possible to use additive-containing catalysts without loss of activity in units which cannot effect gas phase start-up or are required to carry out a pressure test. The organic liquid may be a hydrocarbon with a boiling range of 150-500 °C, preferably gasoline, white spirit, diesel, gas oil, mineral lube oil, or white oil. The step of contacting the catalyst with hydrogen and a sulphur-containing compound may take place in one step at a temperature of 150-450 °C. It may also take place in two steps, with the first step being performed at a temperature which is lower than that of the second step, with the first step being carried out at a temperature of 100-250 °C and the second step at a temperature of 150-450 °C.
