Title (EN) METHOD FOR FAST SHAPING CARBON SUPPORTED METAL CATALYST POWDERS INTO FLEXIBLE PLATES VIA SUBSEQUENT COLD AND HOT COMPRESSION MOULDING
(FR) PROCÉDÉ POUR LA MISE EN FORME RAPIDE DE POUDRES DE CATALYSEUR MÉTALLIQUE SUR SUPPORT DE CARBONE EN PLAQUES FLEXIBLES PAR L’INTERMÉDIAIRE DE MOULAGES PAR COMPRESSION CONSÉCUTIFS À FROID ET À CHAUD
Abstract:
(EN) The proposed invention describes a manufacturing method for fast shaping of carbon supported metal catalysts into plates with required elasticity and hardness, by means of cold and hot press techniques and by using binders. Preparation of the plates occurs through four stages: (1) Preparation of a dry mixture of polymeric binder in powder form and carbon supported metal catalyst in powder form; (2) Homogenization of this mixture at high mixing speed; (3) Spreading the homogenized mixture over the mould as thin layer and pressing at ambient temperature for a short period of time; (4) Removing the plate from the mould and re-pressing at high temperature and under pressure for a short period of time after covering the cold pressed plate with a metallic foil.
(FR) L'invention proposée concerne un procédé de fabrication pour la mise en forme rapide de catalyseurs métalliques sur support de carbone en plaques dotées d'une élasticité et d'une dureté requises, au moyen des techniques de pressage à froid et à chaud et en utilisant des liants. La préparation des plaques se déroule en quatre phases : (1) préparation d'un mélange sec de liant polymère sous forme de poudre et d'un catalyseur métallique sur support de carbone sous forme de poudre ; (2) homogénéisation de ce mélange à une vitesse de mélange élevée ; (3) étalement du mélange homogénéisé par-dessus le moule sous forme de couche mince et pressage à la température ambiante pendant une courte période de temps ; (4) retrait de la plaque du moule et nouveau pressage à haute température et sous pression pendant une courte période de temps après avoir couvert la plaque pressée à froid avec un film métallique.
