Claims
- 1. A boro-aluminosilicate composition selected from EU1 and intergrown mixtures of EU1 and NES boro-aluminosilicate topology zeolites, said boro-aluminosilicate composition prepared by treating a boro-aluminosilicate containing detrital material with a base for a time and at a temperature sufficient to remove said detrital material from said boro-aluminosilicate composition wherein said boro-aluminosilicate composition has a Si/M ratio of >about 50.
- 2. The composition of claim 1 wherein said composition has improved wax isomerization properties.
- 3. A boro-aluminosilicate according to claim 2 wherein said improved wax isomerization properties include an activity improved by a factor of at least two and an improved selectivity.
- 4. The composition of claim 1 wherein said base has a concentration of about 0.5 normal or less.
- 5. The composition of claim 1 wherein said base has a concentration of about from 0.1N to about 0.4N.
- 6. The composition of claim 1 wherein said base is selected from the group consisting of LiOH, NaOH, KOH, RbOH, CsOH, Ca(OH)2, Sr(OH)2, Ba(OH)2 and mixtures thereof.
- 7. The composition of claim 1 wherein said NES topology boro-aluminosilicate zeolite is selected from the group of NU-85, NU-86, and NU-87 zeolites and mixtures thereof.
- 8. A catalytic isomerization process comprising contacting a feedstock comprising a C16 to C46 carbon containing feedstock under catalytic isomerization conditions with a catalyst comprising the boro-aluminosilicate zeolite of claim 1.
