Conclusions

  1. 1.

    The inhomogeneity of the Al2O3 surface associated with the existence of acid and basic regions has a considerable influence on the dehydrogenating activity of gas-adsorption AC catalysts.

  2. 2.

    The dehydrogenating activity of AC catalysts is determined not by the total Cr2O3 content but only by that proportion situated in optimum regions of a basic character, which constitute only a small proportion of the total number of regions.

  3. 3.

    It would appear that the Al2O3 here studied has approximately the same numbers of acid and basic Lewis centers.
