Definitions

  • the present invention relates to the production of activated textures in carbon fibers.
  • Such textures are especially usable for the filtration of fluids, for example the treatment of gaseous or liquid effluents.
  • cellulose flame retardants These constituents which promote the dehydration of cellulose are also known as cellulose flame retardants. They allow carbonization of the cellulosic precursor with better yield and faster kinetics.
  • Achieving an activated carbon fiber texture includes then a treatment to activate the carbon fiber texture by the action of an oxidizing gas, for example carbon dioxide, water vapor or air, to a temperature above 500 ° C, typically 600 ° C to 1000 ° C, i.e. a temperature higher than that of charring.
  • an oxidizing gas for example carbon dioxide, water vapor or air
  • An activation technique of carbon fabric in an oven is described in the document FR-A-2 741 363.
  • n ° 38 (C-004) (JP-A-55-010472) which describe the activation of fiber textures carbon previously obtained by carbonization of a cellulosic precursor to which a cellulose dehydration promoter (chloride ammonium, phosphoric acid and zinc chloride, for example).
  • a cellulose dehydration promoter chloride ammonium, phosphoric acid and zinc chloride, for example.
  • activation techniques require heat treatment specific. They have a relatively low overall mass yield, by compared to the texture of cellulosic fibers, the activation treatment having for effect of creating a microporous network by elimination of carbon. The price of returns is very high, the carbon fiber textures activation supports being themselves expensive. In addition, activation significantly affects the mechanical qualities of carbon fibers, and we observe that the documents cited above do not, in general, state the properties mechanics of activated carbon fibers.
  • the present invention aims to provide a method for obtaining activated textures in carbon fibers, from fibers in carbon precursor of the cellulosic type more economically and with a much higher yield than in the prior art.
  • the invention also aims to provide a method for to obtain activated textures in carbon fibers having good hold mechanical and retaining high flexibility allowing them to be shaped, for example by draping.
  • a process for producing an activated texture of carbon fibers comprising the steps which consist in providing a texture in fibers of cellulosic material, carbon precursor, impregnating the texture with a composition containing at least one constituent mineral having a function of promoter of the dehydration of the cellulose, and carrying out a heat treatment of the impregnated texture at a temperature sufficient to cause the transformation of the cellulose precursor essentially into carbon and to obtain a texture in carbon fibers, is characterized in that the carbon precursor cellulosic material is chosen from rayon, fibrane, solvent celluloses, cotton and bast fibers, and the heat treatment is carried out under an inert or partially oxidizing atmosphere, consists of a rise in temperature at an average speed between 1 and 15 ° C / min followed by a plateau at a temperature between 350 ° C and 500 ° C, and is followed by a step of removing residual phases of the impregnation composition and of degradation products of the cellulosic material by washing the texture, so
  • the invention is remarkable in that the phases of carbonization and activation are carried out in a single heat treatment, at a temperature moderate and result in an activated texture with a very specific surface high.
  • the yield measured by the ratio between the texture mass activated and the starting texture mass of cellulosic fibers is greater than 30%, typically between 35% and 45%, therefore high.
  • the duration of the stage of the heat treatment is preferably at most equal at 1 a.m.
  • the liquid composition for impregnating the texture in fibers of cellulosic material contains at least one mineral constituent and solid fillers, these being for example chosen from antimony, iron, titanium and silicon.
  • the heat treatment and washing steps are carried out continuously, thanks to the good mechanical strength of the texture
  • the process can be implemented on different fibrous textures, in particular wires, cables, fabrics, unidirectional layers of wires or multidirectional, felts, mats, knits, sheets and films.
  • the initial fibrous texture is made of carbon precursor fibers of cellulosic type, for example in rayon multifilaments, in yarn of viscose (fibranne), of cellulose fibers or filaments containing solvent, of cotton or even bast fibers.
  • the texture of cellulosic fibers is impregnated with a composition containing at least one constituent having a function of promoting the dehydration of cellulose.
  • constituents are well known in themselves and are at least, for some, also used as flame retardants for cellulose.
  • One or more mineral constituents may be used chosen from phosphoric acid (H 3 PO 4 ), sulfuric acid (H 2 SO 4 ), hydrochloric acid (HCI), diammonic phosphate ((NH 4 ) 2 HPO 4 ), sodium phosphate (Na 3 PO 4 ), potassium sulfate (K 2 SO 4 ), ammonium chloride (NH 4 CI), zinc chloride (ZnCl 2 ), any phosphorus salt or boron, and generally Lewis or Brönsted acids.
  • a mixture of several constituents may have a beneficial effect on the mechanical strength of the final texture obtained, if they are chosen for promote the dehydration of cellulose at different times of the treatment thermal and therefore make the reaction less violent.
  • Different solid fillers can be added to the composition impregnation in order to constitute impurities which favor the development of the microporous network during heat treatment.
  • catalyst component (s) in the dehydration of the cellulose depends on the nature of the constituents. She is chosen, in a way general, high enough to generate a large specific surface in the activated texture, but without being excessive, which would lead to a texture fragile (brittle) and rigid.
  • the heat treatment includes a first phase of rise progressive in temperature, followed by a plateau.
  • the temperature rise must be fast enough to obtain a large specific surface, but without excessive speed for achieve controlled degradation of the cellulose and obtain an activated texture final with good mechanical strength.
  • the average rate of climb in temperature is between 1 and 15 ° C / min, the temperature increase not necessarily being linear over time.
  • the plateau at the final heat treatment temperature allows complete the degradation of cellulose. It is important, however, not to exceed a maximum value beyond which a risk of closure of microporosities has been observed.
  • Final processing temperature is understood between 350 ° C and 500 ° C.
  • the heat treatment (temperature rise and level) is carried out under an inert atmosphere, for example under nitrogen, or partially inert.
  • an inert atmosphere for example under nitrogen, or partially inert.
  • oxygen from the air, dioxide of carbon, water vapor or other oxidizing agents especially generated by the decomposition of the constituent (s) of the impregnation composition.
  • the final washing of the activated texture is preferably carried out immediately after heat treatment to avoid blockage of microporosities created, an obstruction that can result from the crystallization of a excess of constituents of the impregnation composition in the micropores, the kinetics of dissolution of these crystals being very slow.
  • Washing with water can include a first phase of solubilization of the constituent (s) of the impregnating composition present in excess on the final texture, then a second rinsing phase. Washing eliminates not only residual phases of the composition impregnation, but also degradation products of the cellulosic material carbon precursor.
