Role of mass transfer and kinetics in the hydrogenation of rapeseed oil on a supported palladium catalyst
TL;DR: In this paper, the contribution of mass transfer to the reaction rates was carefully evaluated by determining the mass transfer parameters according to independent routes, and a more general kinetic model was developed based on a complex scheme of simultaneous and consecutive reactions where hydrogenation reactions occur together with cis-trans isomerizations.

Solid‐liquid mass transfer coefficients in gas‐solid‐liquid agitated vessels
TL;DR: In this paper, a dissolution technique was used to measure the solid-liquid mass transfer coefficient in gas-solid-liquid vessels stirred by either radial or axial impellers, and the mechanical power dissipated by the stirrers at various agitation speeds and gas flow rates was also measured by means of a new technique.
