FIELD: various-destination catalysts.
SUBSTANCE: invention provides a novel crystalline aluminosilicate zeolite family depicted by general formula MmRrAl(1-x)ExSiyOz, 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.
EFFECT: extended assortment of zeolite-type catalysts.
