Reactors

Question 1

Give the Reactor Qualifications and briefly describe each

Answer 1

● Conversion (X) difference in amt of A and B after the reaction
● Yield (Y)
● Selectivity (S) measure of how much of the desired product is formed
● Productivity (L) amt of product per time
● Space Time Yield (STY) amt of produce/volume/hr

Question 2

What is the Goal for an optimum reactor Reactor Qualifications

Answer 2

Maximize the Yield

Question 3

Give the major classifications of reactors

Answer 3

● Mode of operation (Batch, Semi, Continuous)
● Arrangement of Catalyst (Fixed Bed, Fluidized Bed)
● Number of Phases (Single Phase, Multi-Phase)

Question 4

Given a parallel reaction:

A₁ → A₂ r₁ = k₁A₁ᴺ
A₁ → A₃ r₂ = k₂A₁ᴹ

where N > M what would be the ideal reactor for an optimized selectivity?

Answer 4

for N > M use PTFR

Question 5

Relate selectivity to reaction constant

Answer 5

S = r₁/r₂ = (k₁/k₂) A₁ᴺ-ᴹ
