The addition to cracked zeolite catalysts of metal of the VIII group increases its cracking activity without changing activity in hydrogen redistribution. Cracking n-heptane in hydrogen increases reaction rate on a CaY catalyst approximately 2.5-fold and on a Pt/CaY catalyst - 30-fold. Regularities observed in the behavior of zeolite and metal-zeolite catalysts may be explained satisfactorily by bifunctional mechanisms of sequential reactions of cracking and redistribution of hydrogen.
