Abstract

Abstract Process for the preparation of a modified zeolite of the Y-type by treatment with a solution of a metal salt and a calcina­tion which comprises treating a zeolite of the Y-type having an alkali oxide/aluminium oxide molar ratio of at most 0.13 with a solution of a multi-valent metal salt having a cationic radius between 0.6 and 1.0 Å and converting the thus treated zeolite by calcination into a product having a unit cell size between 24.21 and 24.65 Å.
