A method for separation of at least one catalyst or adsorbent from a homogeneous mixture of catalysts or adsorbents, used in a method for treatment of gas or hydrocarbon feedstock, in which the grains of catalysts or adsorbents are separated according to a sorting threshold corresponding to a content of the constituent element that is sought and defined by the user.

Method for compositional sorting of catalyst or adsorbent in mixtures of catalysts and/or adsorbents

A process for producing hydrogen sulfide from hydrogen and elemental sulfur, comprising:

Process for producing hydrogen sulfide in a circulating catalytic bed reactor

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&#xb0; 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&#xb0; 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&#x2212;60&#xb0; C. to T&#x2212;1&#xb0; C., while remaining no lower than 40&#xb0; C.

Method for limiting the emission of dust from catalyst grains

A method and a device for separation of at least one catalyst and/or adsorbent from a homogeneous mixture of catalysts and/or adsorbents containing one or more metal, semi-metal or non-metal contaminant(s) deposited thereon, making it possible to separate catalysts or adsorbents according to the presence or absence of contaminant and also according to the contaminant content, starting from a sorting threshold that corresponds to a content and that is defined by the operator.

Method for sorting contaminated catalysts or adsorbents

A process is disclosed for limiting the emissions of gases from a porous material in the form of particles comprising a porous inorganic support and at least 0.1% by weight of one or more compounds chosen from organic compounds, halogen compounds, boron compounds and phosphorus compounds. The particles are placed in motion within a hot gas stream traversing them, and a liquid composition containing one or more film-forming polymer(s) is sprayed over the moving particles by means of a twin-fluid atomization nozzle, in which the liquid composition is mixed with a pressurized gas, with a relative atomization pressure of greater than or equal to 0.7&#xd7;100Pa, until a protective layer containing the film-forming polymer(s) and exhibiting a mean thickness of less than or equal to 20 &#x3bc;m is obtained on the surface of the said particles. A material resulting from this process is also disclosed.

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 &#x3bc;m. 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.
