Abstract

Coherently grown composites of two zeotypes are described. The coherently grown composites have a crystalline three-dimensional framework of at least AlO 2 and PO 2 tetrahedral units. The two zeotypes are selected from the group consisting of AFX, LEV, CHA, and ERI. Methods of making the coherently grown composites are also described.

First claim

What is claimed is:

1 . A coherently grown composite of two zeotypes having a crystalline three-dimensional framework of at least AlO 2 and PO 2 tetrahedral units, the two zeotypes selected from the group consisting of AFX, LEV, CHA, and ERI.

2 . The coherently grown composite of claim 1 having an empirical formula expressed in molar ratios of:
m R:(Si x Al y P z O 2 )

where R represents at least one organic template present inside the pores of the molecular sieve; m is the molar ratio of R to (Si x Al y P z O 2 ) and has a value of about 0 to 0.5; x is the mole fraction of silicon and has a value from about 0 to 0.6; y is the mole fraction of aluminum and has a value from about 0.01 to 0.6; z is the mole fraction of phosphorus and has a value from about 0.01 to 0.55; and x+y+z=1.

3 . The coherently grown composite of claim 2 wherein the two zeotypes are AFX and LEV.

4 . The coherently grown composite of claim 2 characterized by an x-ray diffraction pattern having at least the d-spacings and intensities set forth in Table 1:
