A method for charging a catalyst into a reactor () comprising a separation loop (), comprising the following steps: 14021. A method for charging a catalyst into a synthesis reactor () , of the bubble column type , comprising a separation loop () , said method comprising the following steps:{'b': 40', '1, 'a) filling at least a portion of the synthesis reactor () with a solvent S;'}{'b': 21', '40', '1, 'b) filling at least a portion of the separation loop () of said synthesis reactor () with said solvent S;'}{'b': 1', '40', '21', '40, 'c) causing said solvent S to move from the synthesis reactor () to the separation loop () and from the separation loop to the synthesis reactor ();'}{'b': '40', 'd) heating the synthesis reactor () to a temperature of 100° C. or less;'}{'b': 40', '40, 'e) injecting an inert gas into the bottom of the synthesis reactor () and increasing the pressure of the synthesis reactor () in a manner such as to obtain an absolute pressure in the range 0.1 to 0.6 MPa;'}{'b': 2', '30, 'f) mixing said catalyst with a solvent S in a vessel () in order to obtain a liquid/solid mixture;'}{'b': 30', '40', '40, 'g) increasing the pressure in the vessel () to a pressure which is at least 0.2 MPa higher than the pressure of the synthesis reactor (), then sending the liquid/solid mixture obtained in step f) to the synthesis reactor ();'}{'b': 1', '2', '40', '21, 'h) withdrawing at least a portion of said solvent S and/or S contained in the synthesis reactor () and/or in the separation loop ().'}212. The method as claimed in claim 1 , characterized in that the solvent S is identical to the solvent S.312. The method as claimed in claim 1 , characterized in that the solvent S and/or the solvent S are selected from hydrogenated polyalphaolefin solvents or hydrogenated isoparaffinic solvents.4. The method as claimed in claim 1 , further comprising the following steps after step h):{'b': '40', 'i) heating the synthesis reactor () to a temperature in the range 150° ...
