The design and construction of a microreactor with an IR transmitting window are described. The microreactor can be used to study heterogeneously catalyzed gas phase reactions in the l00–600°C temperature range by analyzing the emitted IR radiation with the aid of a Fourier transform infrared spectrometer. The reactor feed can be prepared so that the reaction conditions correspond to a practical, heterogeneously catalyzed, gas phase reaction system. Product stream monitoring can be carried out to determine whether the IR emission spectra obtained originate from a stationary state in the catalytic reaction. Some results obtained with the present microreactor are given.
