摘要： The invention provides a process for limiting self heating of activated particle catalysts wherein the catalyst particles are placed in motion inside a hot gas flow that passes through them and a liquid composition containing one or several film forming polymer(s) is pulverized onto the particles in motion until a protective layer is obtained on the surface of said particles containing said film forming polymer and having an average thickness of less than or equal to 20 μm. The invention also provides the use of this process to reduce the quantities of toxic gases that may be emitted by the activated catalysts, as well as an activated catalyst for the hydroconversion of hydrocarbons covered with a continuous protective layer that are obtained by this process.

摘要： The present invention includes a method for emptying a reactor containing at least one bed of spent catalyst particles and that comprises at least one dump tube, which opens into the reactor in the bottom portion of the bed of particles or underneath the latter. The method comprises the following:
a first step of causing a proportion of the catalyst bed to flow out of the reactor via said dump tube; then
a second step of expelling out of the reactor the catalyst remainder, by driving towards the opening of the dump tube the catalyst particles remaining in the reactor at the end of the first step, this step being performed by means of a removable device introduced into the reactor via the dump tube,
and is characterised in that said removable device comprises an articulated arm bearing one or more protuberances spirally disposed about a rotary axis.-

摘要： 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.
