Summary

  1. 1.

    A study has been made of the catalytic properties of aluminum-chromium-potassium catalysts of various compositions as exhibited in the dehydrogenation of isopentane to isoamylenes.

     
  2. 2.

    A comparison has been made between the catalytic and some other properties of the ACP catalysts and their surface features and structure.

     
  3. 3.

    The most active ACP catalysts were the ones which contain 9–17% chromium oxide and 2–3% by weight of potassium oxide and had the smallest pore diameters (38–45 A) and the largest specific surface (175–183 m2/g).

     
  4. 4.

    The spinel structure phase is catalytically more active than the corundum phase in dehydrogenating isopentane to isoamylenes.

     
  5. 5.

    The maximum activity of ACP catalysts in the dehydrogenation of isopentane to isoamylenes occurs for the composition which gives maximum strength.
