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 isomerisation and alkylation.
Claims24
A process for effecting catalytic conversion of an organic charge which comprises contacting said charge under catalytic conditions with a catalyst comprising a zeolite designated NU- 85, said zeolite being an intergrowth of zeolites EU-1 and NU-87, and having a composition expressed on an anhydrous basis (in terms of mole ratios of oxide) by the formula:
- 100XO.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
- wherein
- R is one or more cations of valency of n;
- X is silicon and/or germanium;
- Y is one of more of aluminum, iron, gallium, boron, titanium, vanadium, zirconium, molybdenum, arsenic, antimony, chromium and manganese;
- and having, in its prepared form, lattice images which, when oriented to show 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 an X-ray diffraction pattern including the lines shown in Table 1.
A process for alkylation or dealkylation of aromatic hydrocarbons, in the presence or absence of hydrogen, employing a catalyst comprising a zeolite designated NU-85, said zeolite being an intergrowth of zeolites EU-1 and NU-87, and having a composition expressed on an anhydrous basis (in terms of mole ratios of oxide) by the formula:
- 100XO.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.
- wherein
- R is one or more cations of valency of 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 prepared form, lattice images which, when oriented to show 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 an X-ray diffraction pattern including the lines shown in Table 1.
A process for catalytically converting an organic compound comprising contacting said compound under catalytic conversion conditions with a catalyst comprising a zeolite designated 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 aluminium, iron, gallium, boron, titanium, vanadium, zirconium, molybdenum, arsenic, antimony, chromium and manganese and having, in its as-prepared form, lattice images which, when oriented to show 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 R being other than hydrogen or at least partially hydrogen.
