Gas/Liquid Mass Transfer in Small Laboratory Batch Reactors:  Comparison of Methods

Abstract: The interest and accuracy of using the physical absorption of hydrogen to determine k L a in small batch reactors (25-300 cm 3 ) are revisited. The results are compared with those obtained by carrying out the hydrogenation of R-methylstyrene, a fast chemical reaction with known intrinsic kinetics.

“…11b). While these values are much larger than the orders of magnitude conventionally found in conventional fixed beds [47], they are close to those found in laboratory scale stirred tank reactors [48]. This can be explained by the rather high liquid retention under these conditions which limits the G-L specific surface area.…”

“…In order to decrease the number of kinetic constants to be determined through numerical adjustment to a more reasonable but still reliable number, k La has been estimated from a correlation developed for a mechanically agitated tank of a similar volume (Eq. (6)) [39].…”
