ABSTRACT:
A process is provided for alkylation or transalkylation of aromatic hydrocarbons by contacting same with an alkylating or transalkylating agent in a reaction zone maintained under alkylation/transalkylation effective conditions and in the presence of a catalyst comprising a crystalline aluminosilicate zeolite characterized by a unique X-ray diffraction pattern, said catalyst under said conditions being capable of affording a high and selective yield of desired alkylaromatic product while maintaining excellent aging properties.
