Crystalline intergrowth material, its synthesis and its use in the conversion of oxygenates to olefins |
摘要 |
A silicoaluminophosphate molecular sieve is disclosed that comprises first and second intergrown phases of a CHA framework type and an AEI framework type, wherein said first intergrown phase has an AEI/CHA ratio of from about 5/95 to about 40/60 as determined by DIFFaX analysis, the second intergrown phase has an AEI/CHA ratio of about 30/70 to about 55/45 as determined by DIFFaX analysis and said molecular sieve has a silica to alumina molar ratio (Si/Al2) from about 0.13 to about 0.24.
