Abstract
The
tube-in-tube reactor is a convenient method for implementing
gas/liquid reactions on the microscale, in which pressurized gas permeates
through a Teflon AF-2400 membrane and reacts with substrates in liquid
phase. Here we present the first quantitative models for analytically
and numerically computing gas and substrate concentration profiles
within the tube-in-tube reactor. The model accurately predicts mass
transfer performance in good agreement with experimental measurement.
The scaling behavior and reaction limitations of the tube-in-tube
reactor are predicted by modeling and compared with gas/liquid micro-
and minireactors. The presented model yields new insights into the
scalability and applicability of the tube-in-tube reactor
