Abstract
A zeolite, designated NU-85, is an intergrowth of zeolites EU-1 and NU-87. The zeolite is a useful catalyst in a wide variety of hydrocarbon conversion reactions including isomerization and alkylation.
Claims4
A catalyst comprising zeolite NU- 85 having a composition expressed on an anhydrous basis, in terms of mole ratios of oxide, by the formula:
- 100 XO.sub.2 :
- less than or equal to 10 Y.sub.2 O.sub.3 :
- less than or equal to 20 R.sub.2/n O
- where R is one or more cations of valency n, X is silicon and/or germanium, Y is one or more of aluminum, iron, gallium, boron, titanium, vanadium, zirconium, molybdenum, arsenic, antimony, chromium and manganese and having, in its as-prepared form, lattice images which, when orientated to show the 20.+-.0.2 Angstrom fringes of zeolite EU-1 exhibit intergrown 12.5.+-.0.2 Angstrom fringes together with said 20.+-.0.2 Angstrom fringes and/or a X-ray diffraction pattern including the lines shown in Table 1 in which R is at least partially hydrogen.
