Sketch qualitatively the reactant, product, and activity profiles as a function of length at various times for a packed-bed reactor for
each of the following cases. In addition, sketch the effluent concentration of A as a function of time. The reaction is a simple isomerization:
A → B
a. Rate law: −rA′=kaCA
Decay law: rd=kdaCA
Case I: kd≪k,CaseII:kd=k,CaseIII:kd≫k
b. −rA′=kaCAand rd=kda2
c. −rA′=kaCAand rd=kdaCB
d. Sketch similar profiles for the rate laws in parts (a) and (c) in a moving-bed reactor with the solids entering at the same end of the reactor as the reactant.
e. Repeat part (d) for the case where the solids and the reactant enter at opposite ends.
