Abstract
An aluminum-rich molecular sieve material of MFS framework type, designated SSZ-123, is provided. SSZ-123 can be synthesized using 1-ethyl-1-[5-(triethylammonio)pentyl]piperidinium cations as a structure directing agent. SSZ-123 may be used in organic compound conversion and/or sorptive processes.
Claims13
A molecular sieve of MFS framework type having a molar ratio of SiO2/Al2O3 in a range of 10 to 35.
A molecular sieve of MFS framework type and, in its as-synthesized form, comprising 1-ethyl-1-[5-(triethylammonio)pentyl]piperidinium cations in its pores.
A method of synthesizing a molecular sieve of MFS framework type, the method comprising:
- (1) preparing a reaction mixture comprising:
- (a) a source of silicon;
- (b) a source of aluminum;
- (c) a source of an alkali or alkaline earth metal (M);
- (d) a structure directing agent comprising 1-ethyl-1-[5-(triethylammonio)pentyl]piperidinium cations (Q);
- (e) a source of hydroxide ions;
- and
- (f) water;
- and
- (2) subjecting the reaction mixture to crystallization conditions sufficient to form crystals of the molecular sieve.
A process for converting a feedstock comprising an organic compound to a conversion product, the process comprising contacting the feedstock at organic compound conversion conditions with a catalyst comprising a molecular sieve of MFS framework type, wherein the molecular sieve has a molar ratio of SiO2/Al2O3 in a range of from 10 to 35.
