Abstract
Official abstract text for this publication.
A new crystalline molecular sieve designated SSZ-105 is disclosed. SSZ-105 is synthesized using N,N-dimethylpiperidinium cations as a structure directing agent. SSZ-105 is a disordered aluminosilicate molecular sieve comprising at least one intergrown phase of an ERI framework type molecular sieve and an LEV framework type molecular sieve.
First claim
Opening claim text (preview).
The invention claimed is: 1. An aluminosilicate molecular sieve composition having a SiO 2 /Al 2 O 3 mole ratio of from 10 to 50 comprising at least one intergrown phase comprising an ERI framework type molecular sieve and an LEV framework type molecular sieve. 2. The molecular sieve composition of claim 1 , having a SiO 2 /Al 2 O 3 mole ratio of from 10 to 25. 3. The molecular sieve composition of claim 1 , wherein the ERI framework type molecular sieve is present in the at least one intergrown phase in a proportion to the LEV framework type molecular sieve of from 5% to 95%, as determined by DIFFaX analysis. 4. The molecular sieve composition of claim 1 , wherein the ERI framework type molecular sieve is present in the at least one intergrown phase in a proportion to the LEV framework type molecular sieve of from 10% to 90%, as determined by DIFFaX analysis. 5. The molecular sieve composition of claim 1 , wherein the ERI framework type molecular sieve is present in the at least one intergrown phase in a proportion to the LEV framework type molecular sieve of from 20% to 80%, as determined by DIFFaX analysis. 6. The molecular sieve composition of claim 1 , wherein the ERI framework type molecular sieve is present in the at least one intergrown phase in a proportion to the LEV framework type molecular sieve of from 30% to 70%, as determined by DIFFaX analysis. 7. The molecular sieve composition of claim 1 , wherein the ERI framework type molecular sieve is present in the at least one intergrown phase in a proportion to the LEV framework type molecular sieve of from 40% to 60%, as determined by DIFFaX analysis.
