PFR vs CSTR

[Prp89]

Hi all...

I'm new to this forum. Can anyone clear my doubt.

Hydrotreater reactor, FCCU reactor- These fall under which category. PFR or CSTR?

These are better conceptualized as plug flow. Ignore the catalyst. In pfr the composition changes through the reactor from inlet to outlet. In a cstr it is the same everywhere in the reactor.

Best wishes,
