Conclusions

  1. 1.

    Temperature intervals have been marked out over which paraffin hydrocarbons and benzene will undergo simultaneous chemical and physical adsorption on an aluminum—chromium—calcium catalyst.

  2. 2.

    The fact that the rate of chemisorption was directly proportional to the pressure indicated that the adsorption complex contained a single hydrocarbon molecule.

  3. 3.

    The chemisorption activation energy increased with rising paraffin molecular weight; it also increased on replacing the potassium of the aluminum—chromium—potassium catalyst with calcium.
