摘要：
A regenerator for an FCC apparatus. The regenerator includes a riser inside of a shell. The riser includes a cone and a cone skirt. An annulus is formed between the riser and the shell. A sealing system for keeping catalyst out of a portion of the annulus comprises a first sealing element and a second sealing element disposed above the second sealing element. The second sealing element comprises a ring having one or more plates being movable to accommodate the thermal expansion of the riser.
