Test Bench Development and Application to a Parametric Experimental Study on the Dynamic Adsorption Capacity of Noble Gases (Kr, Xe) in the Metal–Organic Framework HKUST-1

Résumé

The objective of this work is to develop a dedicated test bench to study the dynamic noble gases trapping by porous materials, and especially by MOF, in a nuclear context. The well-known coppercontaining HKUST-1 material is used to determine the influence of different parameters such as 2 temperature, concentration, humidity, MOF bed height or diameter, and velocity of the flowrate on noble gases adsorption (Kr, Xe) in breakthrough sorption experiments. Breakthrough time is shown to be directly related to MOF bed height, shaping and gas flow velocity. The adsorption capacities depend on the concentration of noble gases in the gas flow, but also on the flow velocity. Indeed, when the velocity increases from 0.15 to 1 cm.s-1 , the adsorption capacity of Xe increases from 3.46 to 5.15 µmol.g-1 at 25 °C and 1 bar, while the breakthrough time decreases from 7.3 to 2.4 min. On the other hand, temperature and the presence of water vapor have a negative effect on noble gas adsorption in HKUST-1.
