Abstract:

The chemical kinetics of the reactions of hydrochloric acid with various concentrations on Yang Xin limestone of Permian age, dolomite of Sinian Period from Sichuan, and marble has been studied in this paper with rotating disk apparatus at high pressure and temperature. The kinetics equations for the reactions of HCL on various were established under the following conditions:80kg/cm minerals ，80℃and a rotating rate of 600 RPM. It was found through experiments that reaction indices for HCL reacting on marble and pure calcite are close to a unit, and on dolomite and impure calcite more than one. Experiments showed that temperature and rotating rate did not affect reaction indices .It was calculated from the experiment data that the reaction activation energy for the HGL acid-dolomite system is 8910 cal/mol。
