Process for the preparation of a cracking catalyst
摘要
The present invention provides a cracking catalyst, containing a rare-earth Y-zeolite and a support, which is characterized in that the rare-earth content in crystal lattice of the rare-earth Y-zeolite is 4-15 wt% of RE 2 O 3 ; the original unit cell size is 2.440 - 2.465 nm; the equilibrium unit cell size of the catalyst after 100% steam-aging treatment at 800 °C for 17 hours is larger than 2.435nm; the rare-earth atom content in the support is 1.0-8.0 wt% of the support. The present invention also relates to a preparation process for the same catalyst.
