Question

Total, volumetric and specific productivities are different.

(a) True

(b) False

The question was posed to me in an online interview.

My doubt stems from Basic Reaction Theory topic in division Homogenous Reactions of Bioprocess Engineering

Answer 1

Right choice is (b) False

To explain I would say: Total, volumetric and specific productivities are interrelated concepts in process design. For example, high total productivity could be achieved with a catalyst of low specific activity if the reactor is loaded with a high catalyst concentration. If this is not possible, the volumetric productivity will be relatively low and a larger reactor is required to achieve the desired total productivity.
