Partiendo de la cáscara molida y tamizada (diámetro&lt;2 mm) del fruto de Jatropha curcas se fabricaron dos pirolizados mediante deshidratación inicial con ácido concentrados (ácido sulfúrico y ácido fosfórico), y posterior pirólisis a 500 ºC. Se verificó, mediante análisis estadístico, que el PAF (elaborado por deshidratación con ácido fosfórico) eliminó el 47,4±1,8 % de las impurezas coloreadas, con respecto al 36,8±1,6 % eliminado por el PAS (elaborado por deshidratación con ácido sulfúrico). Los parámetros de calidad del PAF se encuentran dentro de los intervalos establecidos para este tipo de material adsorbente. Ninguno de los pirolizados contaminó el jugo clarificado. Teniendo en cuenta los resultados, se sugiere la introducción de estos materiales en el proceso productivo de la industria azucarera.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT In this work, two adsorbents were prepared from the Jatropha curcas fruit shell to evaluate its effectiveness in the colored impurities remotion present in the clarified juice, which is obtained from the sugarcane industry. Using milled and sieved Jatropha curcas fruit shell (diameter &lt;2 mm), two pyrolized were produced, by initial dehydration with concentrated acids (sulfuric and phosphoric acid), and subsequent pyrolysis at 500 °C in nitrogen atmosphere. It was verified, by statistical analysis, that PAF (elaborated by phosphoric acid dehydration) eliminated 47,4±1,8 % of the colored impurities compared to 36,8±1,6 % eliminated by PAS (elaborated by sulfuric acid dehydration). The quality parameters of the PAF are within the ranges established for this type of adsorbent material. None of the pyrolized materials contaminated the clarified juice. Considering these results, can be suggested the introduction of these adsorbent materials into the productive process of the sugarcane industry.]]></p></abstract>
