Beschreibung
Zusammenfassung:	Microspheroidal particles, suitable as fluidized bed catalyst supports, are prepared by incorporating a portion of small, preferably recycled, particles into a slurry of inorganic oxide sol and inorganic particles which is spray dried to form microspheroidal particles. L'invention concerne des particules microsphéroïdales pouvant servir de supports de catalyseurs à lits fluidisés et que l'on prépare en mélangeant une portion de petites particules, recyclées de préférence, à une boue constituée d'un sol d'oxyde inorganique et de particules inorganiques que l'on sèche par atomisation pour obtenir des particles microsphéroïdales.
