TL;DR: In this paper, the feasibility of inferring information of the underlying dynamics in bubble columns, using a set of axially aligned detectors (AADs), was explored using a data mining procedure to determine quantitative indexes related to the underlying flow regime.

TL;DR: In this paper, the effect of slow ON-OFF liquid flow modulation on the yield of consecutive reactions was investigated for oxidation of aqueous ethanol solutions using a 0.5% Pd/Al2O3 commercial catalyst in a laboratory trickle-bed reactor.
Abstract: The effect of slow ON-OFF liquid flow modulation on the yield of consecutive reactions is investigated for oxidation of aqueous ethanol solutions using a 0.5 % Pd/Al2O3 commercial catalyst in a laboratory trickle-bed reactor. Experiments with modulated liquid flow rate (MLFR) were performed under the same hydrodynamic conditions (degree of wetting, liquid holdup) as experiments with constant liquid flow rate (CLFR). Thus, the impact of the duration of wet and dry cycles as well as the period can be independently investigated. Depending on cycling conditions, acetaldehyde or acetic acid production is favored with MLFR compared to CLFR. Results suggest both the opportunity and challenge of finding a way to tune the cycling parameters for producing the most appropriate product.
