Title:
CATALYST COMPOSITION FOR CATALYTIC CRACKING OF HYDROCARBON
Document Type and Number:
Japanese Patent JP2006150183
Kind Code:
A
Abstract:

To provide an aluminum-reinserted type Y zeolite catalyst composition having specified properties and exerting excellent effects when used in catalytic cracking of heavy hydrocarbons, especially residual oil.

The catalyst composition for catalytic cracking of hydrocarbons comprises an aluminum-reinserted type Y zeolite having properties of (a)-(g) and an inorganic oxide matrix: (a) a unit lattice constant, UD, of 24.25-24.60, (b) a degree of crystallinity of ≥95%, (c) a specific surface area of ≥500 m2/g, (d) a total volume, PVt, of the group of micro pores of a 600 or smaller diameter of 0.45-0.70 ml/g, (e) a total volume, PVm, of the group of micro pores of a 100-600 diameter of 0.10-0.40 ml/g, (f) a total volume, PVs, of the group of micro pores of a 35-50 diameter of 0.03-0.15 ml/g and (g) a ratio of tetra-coordinated aluminum atoms to all the aluminum atoms in the zeolite of ≥60 atom%.
