Abstract

Cette invention se rapporte au domaine des matériaux à base de carbone et de graphite, et concerne essentiellement la production de graphite expansé par voie thermique que l'on utilise principalement comme sorbant ainsi que dans la production de feuilles de graphites, de revêtements résistants à la chaleur et au feu, de joints, etc. Ce procédé de production de graphite expansé par voie thermique consiste à doser une poudre de graphite oxydé, à générer un flux à deux phases de particules de poudre dans un gaz, à envoyer ce flux dans la zone de choc thermique d'une unité de chauffage tubulaire dont la température varie de 950 à 1400 °C, puis à extraire le graphite expansé de l'unité de chauffage et à le refroidir. L'unité de chauffage tubulaire est disposée verticalement, tandis que le flux à deux phases est envoyé dans ladite unité de chauffage tubulaire depuis le bas à une vitesse au moins égale à la vitesse de flottement des particules de graphite oxydé. Le refroidissement du graphite expansé se fait lors de son extraction de l'unité de chauffage par un conduit incliné ou horizontal. Le rapport volumétrique entre la poudre et le gaz, lors du dosage et de la génération du flux à deux phases, varie de préférence de 1: 750 à 1: 1400. La durée de séjour minimale des particules dans l'unité de chauffage tubulaire varie de 0,1 à 0,4 secondes.
