Abstract
A fixed bed catalytic microreactor, incorporating repetitive injection gas chromatography/mass spectrometry effluent analysis, is described. The microreactor temperature can be kept constant or varied to permit non-isothermal analyses such as temperature-programmed desorption measurements. Applications of the microreactor system for HZSM-5 and sulfated zirconia catalyst characterizations are described. The use of repetitive injection gas chromatography/mass spectrometry to generate structure-specific volatile product evolution profiles is described for 1-butene oligomerization and n-hexane cracking reactions.
