Abstract

The invention concerns a new stabilized and dealuminated zeolite of OMEGA structure, characterized by: PA0 a total SiO.sub.2 /Al.sub.2 O.sub.3 molar ratio of at least 10, PA0 a sodium content lower than 0.5% by weight, PA0 a and c parameters of elementary mesh respectively lower than 1.814 nm and 0.759 nm, PA0 a nitrogen adsorption capacity at 77 K higher than about 5% by weight for a partial pressure P/P.sub.o of 0.19, PA0 a lattice of mesopores whose radii range preferably from 1.5 to 14 nm. This zeolite can be used in admixture with a convenient matrix in reactions of hydrocarbon conversion.
