Liquid-solid mass transfer in a three-phase stationary catalytic basket reactor
Résumé
Measurements of the liquid-solid mass transfer coefficient k[S] were performed in a three-phase multiple impeller and stationary catalytic basket reactor, called a Robinson-Mahoney reactor. Local coefficients were determined using naphtol particle dissolution in water and n-heptane with or without gas flow. Experiments have shown that local coefficients k[S loc] depend on the particle position in the basket, agitation speed, and liquid properties. A correlation linking k[S] to liquid velocity was established in a reactor simulating hydrodynamics in a piece of catalytic basket. Liquid velocity values were validated using a particle image velocimetry technique in a Robinson-Mahoney reactor, using water.
