Beschreibung
Zusammenfassung:	An apparatus is presented for the transferring of catalyst from an upstream vessel to a downstream vessel. The apparatus includes a non-mechanical valve and a transfer line, wherein a lift gas provides for carrying catalyst through the transfer line. The non-mechanical valve has a catalyst inlet and a lift gas inlet to provide for a consistent flow of catalyst and lift gas to the transfer line. L'invention concerne un appareil pour le transfert de catalyseur d'un récipient amont à un récipient aval. L'appareil comprend une soupape non mécanique et une ligne de transfert, un gaz de levage transportant un catalyseur à travers la ligne de transfert. La soupape non mécanique a une entrée de catalyseur et une entrée de gaz de levage pour fournir un débit régulier de catalyseur et de gaz de levage à la ligne de transfert.
