Conclusions

  1. 1.

    The reaction of water vapors with calcium aluminate components and carriers based on calcium aluminates was investigated by the methods of thermal desorption, differential thermal, and x-ray diffraction analysis. It was shown that C12A7 determines the high specific adsorption of water vapors and the shape of the thermal desorption spectrum. The specific adsorption of water vapors increases, and two forms of adsorption occur instead of one with an increase in the treatment temperature when the concentration of the C12A7 phase increases.

  2. 2.

    The gas-phase reaction of water vapors with the calcium aluminate components of catalysts, in contrast to the liquid-phase reaction, is not accompanied by a change in the phase composition, which makes it possible to widely use them in processes involving water vapors.
