Bentonite (/ ˈ b ɛ n t ə n ʌ ɪ t /) is an absorbent aluminium phyllosilicate clay consisting mostly of was named by Wilbur C. Knight in 1898 after the Cretaceous Benton Shale near Rock River, Wyoming.. The different types of bentonite are each named after the respective dominant element, such as potassium (K), sodium (Na), calcium (Ca), and aluminium (Al).
Bentonite has layer structures and a potential to be used as solid catalyst by activation process. Three methods of activation process had been conducted,namely 60°Cheating; 60°Cheating followed by 1 week settling and 2 weeks settlement. Each method was performed in sulphuric acid and the chemical content of Al 2O3 and SiO2 was observed. An
