Conclusions

  1. 1.

    Synthetic type Y zeolites are active in the disproportionation of propylene, which is accompanied by a redistribution of hydrogen with the formation of saturated hydrocarbons and condensation products.

     
  2. 2.

    The most active of the catalysts studied are [4.7% Ni]/CaY, CaY-90, CaY-56, [4% Ni]/NaY, and the most selective NdY-63, 4.7% Ni/CaY, [4% Co]/NaY, 4.7% Ni/DY.

     
  3. 3.

    The selectivity of the catalysts with respect to disproportionation depends on their composition, method of preliminary treatment, and experimental conditions.
