Abstract

A new method for the in situ measurement of combined adsorption/reaction rates in a catalytic micro-reactor is presented. The measurement is based on the monitoring of the gas flowrate leaving a reactor. Changes of this flowrate due to reaction or adsorption processes are termed the flux response of the system. Flux responses for the decomposition of methanol over Pt/alumina are presented. The development of a model to describe the observed flow fluctuations is discussed.
