A colloidal suspension of LEV structure type crystalline molecular sieve, making the suspension by washing smaller crystallites from a previously found solid LEV product, and using the suspension as seeds in further crystalline molecular sieve syntheses.

Crystalline molecular sieves

Crystalline molecular sieve particles of a size suitable for use as seeds in molecular sieve manufacture are obtained by washing larger particle sized product to dislodge smaller particles from the larger.

Molecular sieves and processes for their manufacture

A process to regenerate iron-based hydrogen sulfide sorbents using steam. The steam is preferably mixed with hydrogen-containing gas and/or an inert gas, such as nitrogen. In a preferred embodiment, the sorbent is first exposed to the steam and then exposed to a hydrogen-containing gas at regeneration conditions.

Regeneration of iron-based hydrogen sulfide sorbents

A process to regenerate metal oxide desulfurization sorbents using an oxidizing and reducing atmosphere. The sorbents may be mono- or multi-metallic in nature, and preferably comprise Cu, Ni and/or Co. If desired, secondary metals may be incorporated to increase regeneration efficiency and/or capacity. Other additives may be used to suppress hydrocarbon cracking. A sorbent containing Zn may be combined with an Fe, Co, Ni, Mo, or W catalyst or a noble metal catalyst and combinations thereof.

Regeneration of hydrogen sulfide sorbents

The present invention provides a method for the synthesis of MeAPO molecular sieves which includes the following steps: providing a source of alumina, a source of phosphorus, water, and a template suitable for forming a MeAPO molecular sieve; providing a source of metal (Me) including metal particles, the metal particles measuring, in their largest dimension, equal to or less than five nanometers; providing a water soluble organic solvent capable of solubilizing the source of metal; forming a synthesis mixture from the source of alumina, the source of phosphorus, the water, the template, the source of metal, and the solvent; and forming a MeAPO molecular sieve from the synthesis mixture.

Method for the synthesis of molecular sieves

Disclosed are silicoaluminates (SAPOs) having unique silicon distributions, a method for their preparation and their use as naphtha cracking catalysts. More particularly, the new SAPOs have a high silica:alumina ratio and favorable Si atom distribution.

Silicoaluminophosphates having an ael structure, a method for their preparation and their use as naphtha cracking catalysts

Disclosed are silicoaluminophosphates (SAPOs) having unique silicon distributions and high catalytic cracking activity a method for their preparation and their use as FCC catalysts. More particularly, the new SAPOs have a high silica:alumina ratio and favorable Si atom distribution. The new SAPOs may have a small crystal size and may be synthesized from a single-phase synthesis solution.

Silicoaluminophosphates having an AEL structure and their use as FCC catalysts

Disclosed are silicoaluminophosphates (SAPOs) having unique silicon distributions and their preparation. More particularly, the new SAPOs have a high silica:alumina ratio, and are prepared from single phase synthesis solutions, or from microemulsions containing surfactants.

Silicoaluminophosphates having an AEL structure, and their preparation

Method for the use of new silicoaluminophosphas having an AEL structure to convert naptha to C2 to C4 olefins

Disclosed are silicoaluminophosphates (SAPOs) having unique silicon distributions and high catalytic cracking activity, a method for their preparation and their use as FCC catalysts. More particularly, the new SAPOs have a high silica:alumina ratio and favorable Si atom distribution. The new SAPOs may have a small crystal size and may be synthesized from a single- phase synthesis solution.

Silicoaluminophosphates having an AEL structure

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

Disclosed are silicoaluminophosphates (SAPOs) having unique silicon distributions, a method for their preparation and their use as catalysts for the hydroprocessing of hydrocarbon feedstocks. More particularly, the new SAPOs have a high silica:alumina ratio, and may be prepared from single phase synthesis solutions or from microemulsions containing surfactants.

Silicoaluminophosphates having AEL structure, a method for their preparation and their use as catalysts for the hydroprocessing of hydrocarbon feedstocks

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 refractory organosulfur heterocycles and aromatics

A process for the hydrodesulfurization (HDS) of multiple condensed ring heterocyclic organosulftir compounds found in petroleum and petrochemical streams. HDS is preferably conducted in a mixed bed containing: (a) a Ni-based catalyst on an inorganic refractory support, and (b) a hydrogen sulfide sorbent material. The desulfurized stream can then be passed to further processing, including aromatics saturation and/or ring opening.
