A rigorous mechanistic model for predicting gas hydrate formation crystallization kinetics is presented and the special case of CO 2 gas hydrate formation regarding CO 2 recovery and sequestration processes has been investigated by using the proposed model. A physical model for prediction of secondary nucleation rate is proposed for the first time and the formation rates of secondary...
Since many years the kinetic models used for interpreting the kinetic curves α(t) relative to the chemical transformations of solids such as thermal decomposition, reduction, oxidation, etc., rely on very restrictive assumptions to which corresponds the following equation:(a)dαdt=A exp−ERTf(α)where A is called the “pre-exponential term”, E is the “apparent activation energy”, and f(α) is a mathematical...
