THE THERMAL DECOMPOSITION KINETICS OF THE REŞADİYE (TOKAT / TURKEY) BENTONITE AND ITS FRACTIONS
Abstract
The untreated bentonite was separated into three fractions by subsequent precipitations from its suspension, during different periods. One fraction remained in suspension during infinite period. Hence, a total of four fractions were separated. Ure activation energies, and pre-exponential factors for the dehydration, dehydroxylation and calcination, of a total of five samples, comprising the untreated bentonite were determined by the Coats — Redfern procedure, using the thennogravimetric data, file decompositions were thought to obey a first order rate law. Their rate equations were written by usingthe determined quantities.
