Abstract
A novel crystalline aluminosilicate composition denominated "zeolite LZ-133" or simply "LZ-133" and having uniform pore dimensions of approximately 4.3 Angstroms is prepared hydrothermally from a reaction mixture containing as essential reagents, water, alkali or alkaline earth metal oxide, alumina, silica and a quaternary ammonium compound.

Crystalline aluminosilicate zeolite composition having a chemical composition in terms of mole ratios of oxides:
- x M.sub.2/n O:Al.sub.2 O.sub.3 :y SiO.sub.2 :z H.sub.2 O
- wherein "M" is at least one cation having the valence "n", "x" has a value of from zero to 3.5, "y" has a value of from 10 to 80 and "z" has a value from zero to 15, said aluminosilicate having an X-ray powder diffraction pattern which does not contain a d-spacing in the range of 4.01-4.03 A and containing at least the d-spacings set forth in Table III or Table IV, the pore diameters of said zeolite being about 4.3 A.
Crystalline aluminosilicate zeolite composition having an as-synthesized chemical composition in terms of mole ratios of oxides:
- a Q.sub.2/n O:b R.sub.2 O:Al.sub.2 O.sub.3 :c SiO.sub.2 :d H.sub.2 O
- wherein "a" has a value in the range of 0.1 to 1.5, Q is an alkali metal or alkaline earth metal cation having the valence of "n", "b" has a value in the range of 0.5 to 2.5, the value of (a+b) is from 0.9 to 3.5, "R" represents the methylquinuclidine ion, "c" has a value of from 10 to 80, "d" has a value of from zero to 15, said zeolite composition having an X-ray powder diffraction pattern which consists essentially of the d-spacings set forth in Table V, the pore diameters of said zeolite being about 4.3A.
