FIELD: various-destination catalysts. n SUBSTANCE: invention provides a novel crystalline aluminosilicate zeolite family depicted by general formula M m R r Al (1-x) E x Si y O z , where M represents alkali or alkali-earth metal such as lithium or strontium, R is nitrogen-containing organic cation such as tetramethylammonium, and E structural element such as gallium. Zeolites are characterized by unique x-ray diffraction pattern and show catalytic properties in hydrocarbon conversion processes, especially in isomerization and alkylation of aromatic compounds. n EFFECT: extended assortment of zeolite-type catalysts. n 18 cl, 18 tbl, 18 ex |
