FIELD: catalysts.
SUBSTANCE: invention relates to zeolites as catalysts for processing exhaust gas. Proposed are an aluminosilicate zeolite with an ITW frame, characterised by phase purity of at least 90% and a ratio of silica to alumina less than 140, an aluminosilicate zeolite with an STW frame, characterised by phase purity of at least 90% and a ratio of silica to alumina less than 100, and an aluminosilicate zeolite with a CHA frame characterised by phase purity of at least 90% and the ratio of silica to alumina of 20 to 500.
EFFECT: creation of zeolites applicable as catalysts.
