Evaluation of desiccant capacity of two zeolites obtained from hydrothermal modification of a red kaolin from Ceará, Brazil

Abstract

The zeolites P e phillipsite previously obtained from hydrothermal reactions in alkaline media of a red kaolin from Ceará, Brazil, were evaluated taking into account the desiccant capacity in ethyl acetate solvents with water in the 0.1-1%vol. range The results show that both zeolites presented good desiccant capacity, with phillipsite having superior performance.
