Abstract
Procédé pour appliquer une matière hydrofuge sur des particules de carbone, et produit ainsi obtenu. On prépare des particules de carbone tamisées entre les mailles normalisées (<< mesh >>) numéro 2 et numéro 30, et une émulsion de polytétrafluoréthylène correspondant à un dosage pondéral de 0,6 % à 20 % de PIFE par rapport au poids des particules. On mélange l'émulsion avec les particules, à raison d'environ 100cm**3 de liquide au maximum, pour 100 grammes de carbone. On chauffe le mélange, pour éliminer l'eau et faire déposer le FTFE sur les particules. La proportion de liquide étant inférieure au taux de saturation des particules, on obtient un dépôt irrégulier et diversifié. Application à la production de particules irrégulièrement hydrofugées, pour améliorer le rendement des réactions catalytiques utilisant de telles particules.
