Abstract: A method for activating a catalyst is described comprising the steps of: (i) installing a reduced and passivated catalyst containing crystallites of a catalytic metal comprising nickel, cobalt or iron in elemental form encapsulated by a layer comprising an oxide of the catalytic metal in a reactor, such as a steam methane reforming reactor, in which it is to be used, and (ii) heating the reduced and passivated catalyst in the reactor under a vacuum or an inert gas to a temperature in the range (TT−X) to (TT+Y), where TT is the Tammann temperature of the catalytic metal in elemental form in degrees Centigrade, X is 400 and Y is 200, to form a catalytically active surface on the catalyst without requiring the application of a reducing gas.

Abstract: A system for use in selective catalytic reduction reactor is disclosed. The system may include a catalyst bed and a screen located close to the catalyst bed in a manner so that flow of flue gas to the catalyst bed contacts the screen before it contacts the catalyst bed. The screen may be adapted to support a weight of at least 400 pounds above the catalyst bed so that the weight is not imposed on the catalyst. The screen may have a plurality of holes across its surface in a manner so that the screen is adapted to change the velocity distribution of the flue gas as it flows through the screen.

Abstract: The present invention relates to a method for producing the activated catalyst for Fischer-Tropsch synthesis comprising: a first step of reducing a catalyst for Fischer-Tropsch synthesis; a second step of preparing liquid hydrocarbon in which a part or all of molecular oxygen is eliminated; and a third step of introducing the reduced catalyst prepared in the first step into the liquid hydrocarbon prepared in the second step while blocking its contact with air. Since the reduced catalyst used for Fischer-Tropsch synthesis is introduced into liquid hydrocarbon from which molecular oxygen is removed or coated by liquid hydrocarbon, the catalyst for Fischer-Tropsch synthesis activated based on the present invention maintains a high activity even if exposed to the air for a long time, thereby easily facilitating the long-term storage and long-distance transfer of the reduced catalyst.

Abstract: 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 0.7×105 Pa, until a protective layer containing the film-forming polymer(s) and exhibiting a mean thickness of less than or equal to 20 μm is obtained on the surface of the said particles. A material resulting from this process is also disclosed.
