OMEGA STRUCTURE ZEOLITE

摘要

The invention concerns a new stabilized and dealuminated zeolite of OMEGA structure, characterized by: a total SiO2/Al2O3 molar ratio of at least 10, a sodium content lower than 0.5% by weight, a and c parameters of elementary mesh respectively lower than 1.814 nm and 0.759 nm, a nitrogen adsorption capacity at 77 K higher than about 5% by weight for a partial pressure P/Po of 0.19, 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.
