A novel apparatus has been developed to enable catalytic reaction mechanisms and kinetic parameters to be determined. It is thought that carbonate formation occurs during fuel reforming chemistries and thus is an important process in these chemistries. Here we perform CO2 SSITKA experiments on gamma-alumina and determine an average surface coverage and residence time at 22 C, 150 C, 350 C, and 420 C. The kinetic parameters of carbonate formation are determined. In addition, the existence of multiple carbonate adsorption sites is elucidated in this dataset by performing a reactivity distribution function (RDF) analyses. Finally, various design characteristics of this newly constructed apparatus will be presented, such as reactor mechanical drawings/experimental layout/materials of construction, FTIR and mass spectroscopy signal-to-noise limitations, and operating temperature range, and transient system response (which is sub-second).
