METHOD FOR FAST SHAPING CARBON SUPPORTED METAL CATALYST POWDERS INTO FLEXIBLE PLATES VIA SUBSEQUENT COLD AND HOT COMPRESSION MOULDING

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 d...

Beschreibung
Zusammenfassung:	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.
