【Abstract】 The carbochlorination technology of rich titanium product is the product of thermodynamics and kinetic theory study. The high-temperature carbonization and low-temperature chlorination of high-titanium blast furnace slag is a typical representative of chlorination metallurgy. Via the free energy analysis,reaction rate and mechanism discussion of Gibbs by TiCl₄ and carbochlorination process,the thermodynamic studies on the carbochlorination process of molten salt and the kinetic model of TiCl₄ are studies,and the thermodynamic trend of carbochlorination reaction,the critical temperature point of CO₂/CO gas production and the commonality of the chlorination reaction being consistent with reduction model of non-reacted nuclear are presented,and the proposal of researching the kinetics and thermodynamics of low temperature chlorination process in high temperature carbonization is put forward.更多还原
