Industrial catalyst development is bene
fi
ting from the use of high throughput research. This is typically
accomplished by running large numbers of experiments in parallel, using common reactant feed
manifolds and analytical systems. In order to
fi
t within a reasonable laboratory footprint, high
throughput reactors must be small, yet retain mass and heat transfer rates that allow gradientless op-
eration. For heterogeneous catalytic reactions there are a number of high throughput systems available
for testing powdered, or granular catalysts in banks of plug
fl
ow reactors, but no reports of CSTR systems
capable of testing formed catalyst particles used in commercial
fi
xed bed reactors.
We describe the development and engineering characterization of a small prototype CSTR for testing
whole catalyst particles. The reactor has inside dimensions of 6.35 cm diameter by 2.8 cm deep and
shows well-mixed behavior, based on methane tracer studies. Sublimation of non-porous cylindrical
naphthalene cylinders (7.5 mm diameter by 7 mm long) was used to characterize the solid
–
gas mass
transfer coef
fi
cient. It was found that the prototype reactor exhibits mass transfer rates similar or higher
than reported in the literature for the much larger traditional Carberry and Berty-style reactors. This
makes the new device suitable for further development of high throughput arrays of CSTRs for testing
commercial catalyst pills
