Abstract
The article is focused on the aspects of using micro-catalytic pulse reactors for studying gas-phase reactions. A literature review includes data regarding different types of micro-catalytic pulse reactor applications in heterogeneous catalysis and the techniques used for estimating kinetic parameters are summarized. The experimental part describes the adaptation of a pyrolysis chromatograph to a micro-catalytic reactor. The mathematical model of a homogeneous pulse carried by the carrier-gas in the plug-flow regime is developed and the assumptions regarding its validity are tested on a model reaction. Three examples describing the application of the technique to non-catalyzed reaction system screening, catalyst screening, and kinetic data measurement followed by estimation of the kinetic quantities of the model reaction by non-linear regression are provided in the article.
