The instant invention is directed to a process for selectively removing detrital material from boro-aluminosilicate selected from EUO, NES and intergrown mixtures of EUO and NES boro-aluminosilicate topology zeolites having a Si/M ratio of greater than about 40, comprising treating said boro-aluminosilicate with a base for a time and at a temperature sufficient to remove said detrital material from said boro-aluminosilicate wherein the concentration of said base is less than about 0.5 normal. Base concentrations in excess of this level may cause the removal of framework components leading to subsequent structural degradation.

Enhanced boro-aluminosilicate EU-1 (LAW778)

A process for the hydrodesulfurization (HDS) of the multiple condensed ring heterocyclic organosulfur compounds and the ring opening of ring compounds present in petroleum and petrochemical streams. The process is conducted in the presence of hydrogen, one or more noble metal catalysts, and a hydrogen sulfide sorbent material.

Desulfurization and ring opening of petroleum streams

A method for preparing novel zeolitic catalyst compositions having a high Si/Al ratio and a crystallinity of at least about 70%. The method involves cation exchanging an as synthesized faujasite material having an Si/Al greater than about 4 with a component selected from the group consisting of ammonium ions and mineral acids, then steam calcining said cation exchanged faujasite in a single steam calcination step at a temperature from about 900.degree. F. to about 1 500.degree. F.

A process for the hydrodesulfurization (HDS) of multiple condensed ring heterocyclic organosulfur compounds present in petroleum and petrochemical streams over noble metal-containing catalysts under relatively mild conditions. The noble metal is selected from Pt, Pd, Ir, Rh, and polymetallics thereof. The catalyst system also contains a hydrogen sulfide sorbent material.

Desulfurization process for refractory organosulfur heterocycles

A process for the hydrodesulfurization (HDS) of multiple condensed ring heterocyclic organosulfur compounds present in petroleum and petrochemical streams and the saturation of aromatics over noble metal-containing catalysts under relatively mild conditions. The noble metal is selected from Pt, Pd, Ir, Rh and polymetallics thereof. The catalyst system also contains a hydrogen sulfide sorbent material.

Desulfurization and aromatic saturation of feedstreams containing

Naphthenic rings in naphthenic ring-containing compounds in a feedstream are selectively opened wherein at least about 50 wt. % of the ring compounds in the feedstream are characterized as containing at least one C.sub.6 ring having at least one substituent containing 3 or more carbon atoms. The naphthenic rings are opened without significant dealkylation of any pendant substituents on the ring. The feedstream, containing such compounds, is contacted with a supported catalyst containing a metal selected from Ir, Ru, or a mixture thereof, which catalyst when reacted with a feed comprised of 20 wt. % n-butylcyclohexane in heptane diluent will result in: a) at least a 10% yield of C.sub.10 paraffin yield/%C.sub.10 ring disappearance.

Process for selectively opening naphthenic rings

This present invention includes a composition of matter made up of a kandite clay which has been treated with large molecules containing multi-atom metallic or semi-metallic species and heated to produce pillars within the clay which are located generally between the clay's layers. The pillared kandite composition is useful as a catalyst support, sorbent, or ion exchanger. The present invention also includes a process for producing the pillared kandite composition comprises mixing the finely divided clay in an aqueous solution with the pillaring medium and heating the resulting composition at a temperature high enough to decompose the added compound.

Pillared metakandite clay compositions as sorbents, catalysts and
