✦ Synopsis

An on-line, computer controlled, automatic experimental setup for the determination of reaction kinetics in gas phase heterogeneous catalytic reactions is presented and demonstrated through the sample study of a simple reaction. The system is automatic to the extent of being capable to carry out. with little or no human intervention, an optimal sequence of experimental runs and single out from a set of plausible rate equations the one that fits best the experimental results. Application of the system to the study of Pt-catalyzed ethylene oxidation around 350°K and atmospheric pressure, showed the classic Langmuir-Hinshelwood rate equation to be significantly more adequate than several other alternatives.
