Abstract

UN PROCEDIMENTO PER LA CLASSIFICAZIONE DI COMPONENTI CATALITICI IN POLVERE, PARTICOLARMENTE PER LA POLIMERIZZAZIONE DI OLEFINE, COMPRENDE L'INVIO AD UNA RETE FILTRANTE DI PARTICELLE SOLIDE SOSPESE IN UN FLUSSO ORIZZONTALE DI GAS DI TRASPORTO. IMMEDIATAMENTE A MONTE DELLA RETE FILTRANTE E' PREVISTO UN CLASIFICATORE AUSILIARIO A LETTO FLUIDIZZATO IN CUI LA SOMMITA' DEL LETTO E' AL LIVELLO DELLA PORZIONE INFERIORE DELLA RETE.
