The present invention relates to a method for limiting the emission of dust from catalyst grains. Said method comprises the following two consecutive steps: a first step of performing a heat treatment of the catalyst grains at a temperature no lower than 100° C., followed by a second step of coating the surface of the catalyst grains by placing same in contact with one or more coating materials having a melting point T no lower than 45° C. and which are injected in a solid state, said second step being carried out with no further addition of heat, at a temperature of T−60° C. to T−1° C., while remaining no lower than 40° C.
