A comparison of the cracking activity and gasoline selectivity on LaX and LaY has shown that LaY is a superior catalyst both in terms of activity and in terms of gasoline selectivity at high conversions. There is reason to believe that the LaX catalyst used in this work was partly diffusion limited within the crystallite and that the activity and selectivity of X catalysts can be improved by producing X sieves in microcrystalline form.
