This work presents an alternative approach for material screening, aiming at investigating under high throughput (HT) conditions key features like kinetic and thermodynamic parameters in catalysis and gas adsorption. A 16-parallel reactor was specifically designed for HT transient screening and kinetics. The fluidic system which enables parallel transient experimentation is detailed. Among its capabilities, this HT equipment allows one to evaluate (i) reaction kinetics under the same ageing conditions for a library of catalysts, and (ii) simplified aging kinetics as well for accessing proper conversion and selectivity data to be modelled. In the domain of adsorption, isotherms of pure component and gas mixtures can be measured by means of parallel breakthrough curve experimentation. The capability, versatility and limits of this equipment are demonstrated through the following case studies: (1) deactivation and kinetic study of o-xylene hydrogenation, (2) characterization of oxygen storage capacity (OSC) of metal/ceria-doped catalysts and (3) HT gas adsorption on mictoporous materials.
