Abstract: Systems and methods are provided for producing lubricant basestocks using a process flow that includes a conversion catalyst that can provide a desired improvement in viscosity index at a reduced or minimized amount of feed conversion. An initial processing stage can be used to produce a lubricant boiling range fraction with a reduced or minimized heteroatom content. After a separation, at least a portion of the lubricant boiling range portion can be exposed to a conversion catalyst that has an effective pore size of at least 8.0 Angstroms, a total surface area of at least 200 m2/g, and/or an Alpha value of 20 or less, where the conversion catalyst includes a supported Group 8-10 noble metal. The methods can allow for increased yields of high viscosity index lubricant boiling range products from a process flow for lubricant base stock and/or blend stock production.

Abstract: Catalysts including at least one microporous material (e.g., zeolite), an organosilica material binder, and at least one catalyst metal are provided herein. Methods of making the catalysts, preferably without surfactants and processes of using the catalysts, e.g., for aromatic hydrogenation, are also provided herein.

Abstract: Systems and methods are provided for producing lubricant basestocks having a reduced or minimized aromatics content. A first processing stage can perform an initial amount of hydrotreating and/or hydrocracking. A first separation stage can then be used to remove fuels boiling range (and lower boiling range) compounds. The remaining lubricant boiling range fraction can then be exposed under hydrocracking conditions to a USY catalyst including a supported noble metal, such as Pt and/or Pd. The USY catalyst can have a desirable combination of catalyst properties, such as a unit cell size of 24.30 or less (or 24.24 or less), a silica to alumina ratio of at least 50 (or at least 80), and an alpha value of 20 or less (or 10 or less). In some aspects, the effluent from the second (hydrocracking) stage can be dewaxed without further separation. In such aspects, a portion of the dewaxed effluent can be used as a recycle quench stream to cool the hydrocracking effluent prior to entering the dewaxing reactor.

Abstract: A hydrocarbon feed stream, particularly one comprising heavier hydrocarbons, may be converted to valuable products such as motor gasoline and/or lubricating oil by employing one or more MOF catalysts, which may be prepared from a precursor metal-organic framework (MOF). A MOF catalyst may be prepared by exchanging one or more organic linking ligands of the precursor MOF for an organic linking ligand having a different acidity and/or electron-withdrawing properties, which, in turn, may affect catalytic activity.

Abstract: Processes are provided for preparing molecular sieves for use as catalysts. The process involves preparing a synthesis mixture for the molecular sieve wherein the synthesis mixture includes a morphology modifier which may be selected from cationic surfactants having a single quaternary ammonium group comprising at least one hydrocarbyl group having at least 12 carbon atoms, nonionic surfactants, anionic surfactants, sugars, and combinations thereof.

Abstract: Methods are provided for performing fluid catalytic cracking (and/or other hydrothermal processing for cracking of hydrocarbons) on a feedstock containing hydrocarbons in the presence of a catalyst that includes zeolite Beta that is stabilized toward hydrothermal conditions. The hydrothermally stabilized zeolite Beta (including any of the various polymorphs) corresponds to zeolite Beta that is formed without the use of an organic structure directing agent, and that is further stabilized by addition of one or more stabilizers, such as lanthanide series elements or phosphorus.

Abstract: Methods are provided for formulation of catalysts with improved catalyst exposure lifetimes under oxygenate conversion conditions. In various additional aspects, methods are described for performing oxygenate conversion reactions using such catalysts with improved catalyst exposure lifetimes. The catalyst formulation methods can include formulation of oxygenate conversion catalysts with binders that are selected from binders having a surface area of roughly 250 m2/g or less, or 200 m2/g or less. In various aspects, during formulation, a weak base can be added to the zeotype crystals, to the binder material, or to the mixture of the zeotype and the binder. It has been unexpectedly discovered that addition of a weak base, so that the weak base is present in at least one component of the binder mixture prior to formulation, can result in longer catalyst exposure lifetimes under methanol conversion conditions.
