摘要：
The present invention relates to a process for the transalkylation of hydrocarbons in the presence of 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 transalkylation of aromatic compounds. The preparation method of the new zeolite is also object of the present invention.
