Abstract

The invention relates to a method for making an open three-dimensional structure made of an inorganic material, in particular carbide, said method comprising: (a) providing a preform made of woven fibres that includes two substantially parallel planes each defining meshes, and each pair formed by two adjacent planes being coupled together by connecting yarns or fibres preferably made of the same material as the woven cellular planes; (b) depositing on the preform a precursor of an inorganic or carbon material by a liquid or gaseous process; (c) carrying out a heat treatment for converting said inorganic or carbon material precursor into a part respectively made of an inorganic or carbon material.

Abstract

The invention relates to a bag (1), intended to contain a pulverulent product, having a wall (2) of tubular general shape defining a pocket, and first and second ends (3, 4), at least one (3) of the ends having flaps which are folded and pasted with glue so as to close the corresponding end (3), the bag (1) additionally having a band (11), made of a tear-resistant material and comprising a handle (12), glued onto the end (3) of the bag so as to cover the flaps. The flaps (6, 7) have a non-pasted portion (8) designed to make them easier to separate, either manually by a user or under the effect of the weight of the pulverulent product when the bag is tilted by the user, and thus form an opening as they are deployed, the band (11) having a non-pasted region (17) which is positioned to face the non-pasted portion (8) of the flaps (6, 7).

Abstract

The invention relates to a method for manufacturing a sulfoaluminous or belitic sulfoaluminous clinker from a raw mix formed from a mixture including minerals containing calcium, aluminum, silica, iron, and sulfur, preferably in sulfate form, and is characterized in that the method comprises the steps including: at least partially dehydrating and decarbonating the mixture through placement in a vertical kiln (1) comprising a substantially vertical chamber (2) wherein the mixture is heated, the chamber (2) of the vertical kiln (1) being supplied with hot gases the temperature of which is between 900 and 1150° C; extracting the dehydrated and decarbonated mixture from the vertical kiln (1) and conveying the same in a continuous kiln (4) comprising a furnace (5) and a transporting means (6) for transporting the mixture across the furnace (5); heating the mixture from the vertical kiln (1) by passing the mixture through the furnace (5) via the transporting means (6) such that a clinkerization of the mixture is obtained, the average passage time in the furnace being greater than 15 minutes.

Abstract

The invention relates to a composite comprising a layer of porous alumina deposited on a rigid substrate made of β-SiC. The composite can be used as a catalyst substrate. The alumina layer may include catalytically active phases, in particular phases that do not properly bind onto the non-treated β-SiC, such as silver particles.

Abstract

The invention relates to a method of producing a composite comprising nanofibres or nanotubes on a porous β-SiC substrate, said method comprising the following steps: (a) a catalyst for growing nanotubes or nanofibres is incorporated into said porous β-SiC substrate or into an SiC precursor; (b) carbon nanotubes or nanofibres are grown from a mixture comprising hydrogen and at least one hydrocarbon; and (c) optionally, said carbon nanotubes or nanofibres are converted to SiC nanofibres. This composite may be used as a catalyst or catalyst support.
