WebFrom Figure 9a it can be clearly seen that geometry 7 performs worse than the other 3 cases on the upper half of the reactor, since it has a lower riser velocity. Geometries 8 and 10 show a similar behavior on the riser, although geometry 8 shows a higher velocity at the top of the reactor which can be due to the contraction-expansion effect. WebThe riser simulator consists of two outer shells, the lower section and the upper section which allow easy loading and unloading of the cata- lyst, as illustrated in Fig. 2. The reactor was...
WebJan 1, 2014 · The reactor temperature is controlled by the regenerated catalyst slide valve. More hot catalyst is circulated to raise the reactor temperature or accommodate increased feed rates.
