CARBON-MINERAL GRANULATED ZEOLITE-BASED ADSORBENT Russian patent published in 1999 - IPC

Abstract RU 2124942 C1

FIELD: sorbents. SUBSTANCE: invention, in particular, relates to binderless zeolite- based adsorbents that can be used for drying and purifying liquid and gas streams to remove metal ions and individual organic components. Natural kaolin, which, if necessary, can be preliminarily supplemented by 20% of amorphous silicon dioxide and mixed with aluminosilicahydrogel with silica/alumina ratio (3-3.5):1, is baked at 600-700 C. Then 1:1 activated carbon/peat mixture is added in quantity 4 to 16% and combined material is stirred until homogeneous plastic stuff is obtained. Material is granulated, dried, and subjected to hydrothermal crystallization. EFFECT: increased dynamic adsorption capacity. 4 ex
