Claims12
A zeolite having an average pore size greater than about 6 Angstroms and having the X-ray diffraction lines of Table I.
A zeolite having a mole ratio greater than about 20 of an oxide of a first tetravalent element to an oxide of a second trivalent or tetravalent element which is different from said first tetravalent element, and having the X-ray diffraction lines of Table I.
A zeolite having a mole ratio greater than about 20 of an oxide selected from the group consisting of silicon oxide, germanium oxide and mixtures thereof to an oxide selected from aluminum oxide, gallium oxide, iron oxide, boron oxide, titanium oxide, indium oxide, vanadium oxide and mixtures thereof, and having the X-ray diffraction lines of Table I.
A zeolite having an average pore size greater than about 6 Angstroms and having, after calcination, the X-ray diffraction lines of Table II.
A zeolite having a mole ratio greater than about 20 of an oxide selected from the group consisting of silicon oxide, germanium oxide and mixtures thereof to an oxide selected from the group consisting of aluminum oxide, gallium oxide, iron oxide, boron oxide, titanium oxide, indium oxide, vanadium oxide and mixtures thereof and having, after calcination, the X-ray diffraction lines of Table II.
