Reactions of hydrocarbons in metal melts

Communication 1. Acceleration and retardation of the cracking of heptane in molten aluminum and sodium

  • 26 Accesses


  1. 1.

    It was found for the first time that the pyrogenetic transformations of heptane in molten aluminum and in molten sodium proceed in a selective manner which depends on the identity of the metal.

  2. 2.

    The extent of the thermal decomposition of heptane is increased by the use of aluminum: in thermal pyrolysis the conversion of heptane (57%) is less than the conversion in contact with aluminum (99%) by nearly one-half.

  3. 3.

    Sodium has a powerful retardant action on the thermal decomposition of heptane: the conversion of heptane in contact with sodium attains only 5–6% at 600–800°.

  4. 4.

    The gas obtained by the pyrolysis of heptane in molten aluminum contains 40–44% of olefins and 12.22% of hydrogen. On the other hand, the pyrolysis of heptane in molten sodium is accompanied by the formation of gas containing 75–85% of hydrogen without any appreciable amount of olefins.
