When a solid catalyst is needed, it is often involved as a thin film deposited on the reactor or channel walls, offering poor catalyst content per volume of reactor. Also, catalyst handling and changeover in case of deactivation are difficult and/or expensive. To face these issues, multiphase micro-packed bed reactors operating with powdered catalysts have been proposed albeit at the expense of very high pressure drop. The alternative concept of open cell solid foam reactor is now well established for gas-solid reactions and more and more works are performed for multiphase gas-liquid or gas-liquid-solid reactors. In the presentation comparisons to other reactors are proposed in terms of hydrodynamics, heat, mass and momentum transfer performances for demanding multiphase gas-liquid and gas-liquid-solid reactions. In particular, demanding hydrogenations and oxidations are performed with the idea is to look for possible synergetic effects by combining G-L segmented flows and open cell solid foams to surpass the characteristics obtained in the two separated systems (low pressure drop, enhanced mixing, good thermal behaviour and mass transfer capacities). |
