(57) Abstract: The invention relates to the activation of bentonite clay. The method comprises mixing crushed bentonite clay and sodium reagent-activator at a relative humidity of clay equal to 20-45%, heating the resulting mixture up to 40-75 o With simultaneous governanee mixture. The method allows to speed up the activation process and improve the quality of clay by improving its physical ...
Read MoreThe modification of the clay was carried out as follows [24, 25]: The Indian bentonite was slurried with water and then mixed with conc. H 2 SO 4 (98%) at predetermined acid/clay ratio of 0.30 so as to form a clay slurry, which was heated on a water bath for 16 h with constant stirring (pH, 1.84). At the end of the reaction time the activation ...
