Determinação do equilíbrio higroscópico e do calor isostérico do bagaço de cana-de-açúcar

摘要: This study aimed to determine the hygroscopic equilibrium and isosteric heat of sugarcane bagasse evaluate sorption dynamics required energy vaporize water in dehydration. The reaction was assessed at different controlled conditions temperature (20, 40, 55 70 oC) air relative humidity (10, 12, 17, 18, 30, 45, 50, 60 85%), as well testing various models described literature identify condition that better represents behavior. As a result, we found model best fit empirical data modified Henderson with determination coefficient 0.972; while integral desorption ranged from 2,524.09 2,951.95 kJ kg-1, for all contents 0.014 until 0.170 bs, respectively.
