Title: | A novel acoustic approach for the characterization of granular activated carbons used in the rum production | Authors: | CRESPO SARIOL, Harold YPERMAN, Jan Brito Sauvanell, Angel CARLEER, Robert Navarro Campa, Jose Gryglewicz, Grazyna |
Issue Date: | 2016 | Publisher: | ELSEVIER SCIENCE BV | Source: | ULTRASONICS, 70, p. 53-63 | Abstract: | Acoustic analysis and sound patterns recognition techniques have been widely used in many branches of science, however; almost none focused on the characterization of granular activated carbon. A new methodology has been developed in order to characterize activated carbon based on the dynamic analysis in audible spectra of the sound's relative amplitude power produced by water flooded on granular activated carbon. A home-build recording set-up and management of acoustic measurements have been presented and correlated with the results of porous structure of carbons characterized by N-2 adsorption. Five samples of granular activated carbons used in the rum production of different exhausted level have been evaluated by both methods. Parameters as the BET surface area and total pore volume showed a satisfactory correlation with acoustic measurement data when the signal is processed at 1000 Hz. Three frequencies components of the produced sound were analyzed and related with the porous characteristics. The found relationship gives the possibility to predict and calculate textural parameters of granular activated carbons applying the acoustic technique. This methodology approach opens possibilities in using acoustic experiments for the characterization of high-porosity materials and to determine their exhausted level. (C) 2016 Elsevier B.V.
