ABSTRACT:
The invention concerns a stabilized and dealuminated omega zeolite, its manufacture and use in catalytic cracking.
It has in particular a SiO.sub.2 /Al.sub.2 O.sub.3 molar ratio higher than 10, a sodium content lower than 0.3%, "a" and "c" crystalline parameters respectively lower than or equal to 1.814 nm and 0.760 nm, a particular capacity for nitrogen adsorption and a particular lattice of secondary pores.
