Hello everyone,
I'm a chemical engineering student and I am having trouble solving example questions on my chemical reaction engineering module about catalyst deactivation. Would really appreciate the help if anyone could explain how to solve the following question. Thank you
The reaction 2A → B is second-order liquid-phase, catalysed, of rate rm = kAm[A] . The products tends to degrade (B → C) and produces coke on the surface of the catalyst, leading to series deactivation of rate
rf ≡1/Am*[dAm]/dt = kf [B]
a) Find the steady state concentrations of [A] and [B] from the (note that it is quasi-steady; ignore the amount of B consumed by the second reaction).
Find Am(t) if [B] changes with time.
c) Design a schedule for the flow rate v that keeps [A] and [B] steady.
