“…Due to the strong turbulent mixing promoted by the use of an impeller, mass transfer coefficients between the phases (gas-liquid and solid-liquid) are usually higher (Pitault et al, 2004). Also, due to the strong agitation, these reactors present lower temperature and concentration gradients (Forni, 1997).…”

“…With the continuous development of newer and more efficient catalysts and the growing interest in the use of complex fluids such as heavy crude feedstock or biomass-derived fluids, the catalyst testing and selection task in lab-scale reactors may become hindered by interphase mass transport limitations, external to the particles, or by mixing limitations. In these cases, measuring the mass transfer coefficients prior to the catalyst kinetic assessment is recommended (Pitault et al, 2004).…”

“…However, the problem of using rotating foam is that the stirring speed is limited and the best performance of rotating foam remained below that of stationary basket at a high stirring speed. Moreover, the use of a gas-inducing impeller with stationary basket widely enhances the Gas-Liquid (GL) mass transfer [13]. Thus, we propose here to combine the advantages of stationary catalytic basket reactor (efficient GL distribution through the stationary basket) and the advantages of foam (high porosity) by replacing the stationary basket with annular foam blocks.…”

“…Una vez sellado se comienza con las condiciones de operación 300 °C, 40 bar de H2 y agitación de 1000 rpm a estas condiciones se evitan limitaciones por fenómenos de transferencia de masa externa e interna, tal como corroboran diversos estudios para este tipo de sistema de reacción [59], [63]. Para realizar las pruebas catalíticas, las reacciones de HDO se llevaron a cabo en un reactor batch de suspensión de tanque agitado marca Parr, modelo 5500 cuyo esquema se representa en la Figura 3.2.…”
