METHOD OF PREPARING HIGH-SILICA ZEOLITES |
| 摘要 |
FIELD: petrochemical process catalysts. SUBSTANCE: high-silica zeolite prepared using ammonium bicarbonate if modified by adding soluble ferric salts to reaction mixture in the hydrothermal synthesis stage. Content of Fe2O3 in resulting zeolite ranges from 0.2 to 3.5%. EFFECT: increased lifetime of resulting zeolite. 1 tbl, 6 ex
