Abstract
Provided is a new crystalline zeolite Fe SSZ-42 prepared by processes for preparing crystalline molecular sieves, particularly large pore zeolites, using an organic templating agent selected from the group consisting of N-benzyl-1,4-diazabicyclo[2.2.2]octane cations and N-benzyl-1-azabicyclo[2.2.2]octane cations.
Claims11
A zeolite having a composition, as-synthesized and in the anhydrous state, in terms of mole ratios as follows:
- SiO2/Fe2O3
- Greater than or equal to 15
- SiO2/MxO
- Greater than or equal to 45
- SiO2/Q
- 10-40
- wherein Q is comprised of cations selected from the group consisting of N-benzyl-1-azabicyclo[2.2,2]octane cations having the structure
- where R is —OH or —NH2, and N-benzyl-1,4-diazabicyclo[2.2.2]octane cations, M is an alkali metal cation or alkaline earth metal cation, x is 1 or 2, and said zeolite having the X-ray diffraction lines of Table I, while containing iron.
