Rehydration Driven Acid Impregnation of Thermally Pretreated Ca-Bentonite—Evolution of the Clay Structure
A new approach to acid activation of raw Ca-bentonite was explored. The method consisted in dehydration of clay by thermal pretreatment at 200 °C, followed by immediate impregnation with H<sub>2</sub>SO<sub>4</sub> solution. The acid concentration was 1.5 × or 2.0 × cation ex...
