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 to limit or reduce pipe erosion and catalyst attrition, as well as to provide catalyst and lift gas to the transfer lines.
