Se determinó el perfil de agotamiento de adsorbedores declarados como agotados en cuatro roneras cubanas. A partir de cálculos desarrollados por modelación matemática de los perfiles se comparó la efectividad neta de manejo del carbón entre roneras, y se demostró que la recuperación y reaprovechamiento de las capas de carbón menos agotadas del lecho es una estrategia que permite elevar la eficiencia de explotación de este costoso recurso para la industria del ron cubano.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT 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 &#8220;out of service&#8221;) 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.]]></p></abstract>
