Conclusions

  1. 1.

    Using seven independent methods it was found that the concentration of the active centers on the surface ofγ-Al2O3, which are responsible for the dehydration, is (9±1)×1017 centers/m2. The catalytically active centers are identical with adsorption centers.

  2. 2.

    A method of calculating the stochiometry, concentration, and thermodynamics of the surface association reactions has been developed.

  3. 3.

    The first reaction step proceeds according to the associative bimolecular substitution mechanism, with the formation of an associative intermediate compound. The association enthalpy and entropy have been calculated.
