Revisiting the maximum conversion of substrate in an enzymatic cstr with micromixing considerations

The balance equations pertaining to an enzyme undergoing first order thermal deactivation and a substrate undergoing enzyme‐catalyzed transformation following Michaelis‐Menten kinetics in a CSTR are solved for the two limits of micromixing. The maximum conversions of substrate are obtained under the assumption that the space time of the reactor is infinite. The range of the maximum conversion of substrate is wider at intermediate values for the dimensionless Michaelis‐Menten constant and becomes narrower as the ratio of the time scales of the enzyme‐catalyzed reaction and the enzyme deactivation increases.
