Abstract
A catalyst comprising a novel zeolite NU-87, is useful in a wide variety of hydrocarbon conversion reactions including isomerisation, transalkylation and alkylation.
Claims22
A process for alkylation or dealkylation of aromatic hydrocarbons in the presence or absence of hydrogen employing a catalyst comprising a zeolite designated NU- 87, said zeolite having a composition expressed on an anhydrous basis (in terms of mole ratios of oxide) by the formula
- 100XO.sub.2 :equal to or less than 10 Y.sub.2 O.sub.3 :equal to or less than 20 R.sub.2/n O
- wherein R with a valency of N is at least partly hydrogen, 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 an X-ray diffraction pattern including the lines shown in Table 2.
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-87, said zeolite having a composition expressed on an anhydrous basis (in terms of mole ratios of oxide) by the formula:
- 100 XO.sub.2 :equal to or less than 10 Y.sub.2 O.sub.3 :equal to or less than 20 R.sub.2/n O
- wherein R with a valency of N is at least in part, hydrogen, 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 said zeolite having an X-ray diffraction pattern including the lines shown in Table 2.
