Résumé

We present here the results of a 3-year project aiming at the development of pilot scale production and shaping of MOFs and at their demonstration in Heat-Pump application at kilogram scale in relevant process conditions. Although MOFs outperform commercial adsorbents for heat-pump application in terms of higher water uptake and cyclability, their commercialisation was until now strongly penalized by their price due to high production process costs. The objective of this program was to develop low cost manufacture processes allowing the production of advanced and cost-competitive adsorbents. We have developed innovative and scalable MOF production processes including synthesis and shaping, for which (i) manufacturing equipment’s are readily available at industrial scale, and (ii) enable upscaling at high production rates whilst achieving high yields, product (sorbent) quality and higher operational safety. We will present three main technological innovations: (i) aqueous synthesis of UiO-66 without the use of corrosive acid modulator (ii) continuous mechano-chemical synthesis on Al-fumarate without solvent and (iii) original scalable shaping process enabling continuous production of robust and size-controlled spheres (beads). In contrast to other adsorbents, we discovered that performances of MOF were jeopardized due to severe mass transport limitations likely due to the organic binder. In order to overcome this limitation small spheres of 0.4 mm (0.3 mm – 0.7 mm) of Al- and Zr-MOF were produced at multi-kg scale. The performances of MOFs were evaluated in 3 liter adsorber demonstrator. We will show that MOFs outperform commercial Silica Gel under standard cycling conditions with stability over 10.000 cycles. Results in extremely low regeneration temperature will be presented and discussed in the frame application market requirements. This work has received funding from the EU under grant agreement No 685727.
