Abstract
The present invention relates to a new zeolite having a beta-type crystalline structure, characterized by a distribution of the Lewis acid sites and Brønsted acid sites corresponding to a molar ratio [Lewis sites] [Brønsted sites] equal to or higher than 1.5. This new zeolite is useful in preparation processes of alkylated aromatic hydrocarbons through the alkylation and/or transalkylation of aromatic compounds. The preparation method of the new zeolite is also object of the present invention.
