LUCAMBIO-MIRO, Liset; MATURELL-PORTUONDO, Amanda M.; LEYVA-ISAAC, Carlos A.  e  CRESPO-SARIOL, Harold. Exhaustion profile and managemet of the activated carbon for industrial contactors in the cuban rum production. Rev Cub Quim [online]. 2022, vol.34, n.2, pp. 315-323.  Epub 14-Jun-2022. ISSN 2224-5421.

In the present study, the ammonia spectrophotometry method (S-NH3) is applied for the exhaustion profile characterization of the activated carbon in fixed bed industrial contactors used in the aged aguardiente refining process for Cuban rum production. The exhaustion profile of industrial contactors (confirmed as “out of service”) from four Cuban rum factories were determined. Based on calculations and mathematical modelling of the profiles, the overall effectiveness in the carbon management was compared between rum factories. In addition, the recovering strategy of the less exhausted carbon layers into the contactor allows increasing the exploitation efficiency for this costly material for the Cuban rum industry.
