FIELD: chemistry.SUBSTANCE: present invention relates to a family of aluminosilicate zeolites, a method of producing zeolites and a method of converting hydrocarbons. Described is a novel family of microporous crystalline aluminosilicate zeolites, having a space frame of at least tetrahedral AlOand SiOunits, wherein the empirical composition of the zeolite in anhydrous state is expressed by the following formula:where M is sodium or a combination of potassium and sodium cations capable of exchange, m is the molar ratio of M to (Al+E) and varies from 0.05 to 2, R denotes a single-charge propyl trimethylammonium cation, r is the molar ratio of R to (Al+E) and varies from 0.25 to 3.0, and E is an element selected from a group consisting of gallium, iron, boron and mixtures thereof, x is the molar fraction or H and varies from 0 to 1.0, y is the molar ratio of Si to (Al+E) and varies from more than 8 to 40, and z is the molar ratio of O to (Al+E) and has a value defined by the equation: z=(m+r+3+4y)/2.EFFECT: said zeolites are characterised by a unique X-ray diffraction pattern and composition, and have catalytic activity for carrying out various hydrocarbon conversion processes.10 cl, 5 tbl, 4 ex |
