Packet M: Bonus 12
A fluidized bed can be used as one of these devices to allow for more uniform particle mixing compared to a packed bed. For 10 points each:
[10m] Name these devices that have “batch” and “continuous stirred-tank” varieties, the latter of which can achieve steady state by receiving reagents (“re-AGE-ints”) at an inlet and expelling products at an outlet.
ANSWER: chemical reactors [accept continuous stirred-tank reactors; accept vat reactors or backmix reactors or mixed flow reactors or continuous-flow stirred-tank reactors; accept batch reactors; accept packed bed reactors; accept fluidized bed reactors; accept reaction vessels; prompt on process vessels; prompt on CSTRs or CFSTRs]
[10h] Continuous stirred-tank reactors can be modelled using a “control” form of this quantity, which is minimized by cascading reactors in series. Residence time equals mass or this quantity divided by the appropriate flow rate.
ANSWER: volume [accept control volume; prompt on V or CV]
[10e] The goal of designing highly efficient reactors is primarily to maximize this quantity, the amount of actual product produced divided by the theoretical maximum.
ANSWER: yield [accept theoretical yield; accept actual yield; accept percent yield]
