Abstract

En este trabajo se determinaron las concentraciones y cantidades de metanol que adsorbieron y desorbieron la zeolita natural y la zeolita modificada con baño ácido, ambas del yacimiento de Palmarito de Cauto en Santiago de Cuba, Cuba. Este proceso permitió determinar la de mejor comportamiento para un sistema de refrigeración por adsorción. La medición de los valores de presión, temperatura y peso, necesarios se realizaron en una instalación experimental. Para trazar el diagrama de Clapeyron representa el ciclo de refrigeración por adsorción se trabajó con temperatura de evaporación de -2 ºC y temperatura de la fuente caliente de 90 ºC. Los resultados obtenidos con la zeolita modificada indicaron que permitía disponer de 8,3 g de metanol por cada kg de adsorbente. La comparación de la capacidad adsortiva de metanol de las zeolitas investigadas con otros tipos de zeolitas internacionalmente comercializadas mostró que los valores de potencia de enfriamiento específica por unidad de masa de adsorbente, estará por debajo de lo esperado.

Palabras claves: refrigeración por adsorción; par zeolita/metanol; evaluación.

Abstract

In this work, the concentrations and quantities of methanol that adsorbed and desorbed natural zeolite and acid-bath modified zeolite, both from the Palmarito de Cauto deposit in Santiago de Cuba, were determined. This process allowed the determination of the best performance for an adsorption cooling system. The necessary pressure, temperature and weight values were measured in an experimental facility. To draw the Clapeyron diagram representing the adsorption refrigeration cycle, we worked with an evaporation temperature of -2 ºC and a hot source temperature of 90 ºC. The results obtained with the modified zeolite indicated that it allowed to have 8,3 g of methanol for each kg of adsorbent. Comparison of the methanol adsorptive capacity of the investigated zeolites with other types of internationally marketed zeolites showed that the specific cooling power values per unit mass of adsorbent will be lower than expected.

Key words: adsorption cooling; zeolite-methanol pair; evaluation.
