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. |
