PROCESS AND APPARATUS FOR MIXING TWO STREAMS OF CATALYST

A process and apparatus for mixing streams of regenerated and carbonized catalyst involves passing a catalyst stream into and out of a chamber in a lower section of a riser. The chamber fosters mixing of the catalyst streams to reduce their temperature differential before contacting hydrocarbon feed...

Zusammenfassung:	A process and apparatus for mixing streams of regenerated and carbonized catalyst involves passing a catalyst stream into and out of a chamber in a lower section of a riser. The chamber fosters mixing of the catalyst streams to reduce their temperature differential before contacting hydrocarbon feed. L'invention concerne un procédé et un appareil pour mélanger deux courants de catalyseur régénéré et carboné et consiste en le passage d'un courant de catalyseur dans et hors d'une chambre dans une section inférieure d'une colonne montante. La chambre favorise le mélange des courants de catalyseur pour réduire leur différence de température avant la mise en contact avec l'alimentation en hydrocarbure.
