Abstract
Abstract Process for the preparation of a zeolitic catalyst which comprises treating a zeolite of the Y-type having an alkali metal 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 combining the ion-exchanged zeolite without a calcination step with a hydrogenation component of a Group 8 and/or Group 6b metal.
