US Classification:

428105, 427470, 977742

Abstract:

Methods are provided for making layer-by-layer assemblies that comprise axial geometry nanoparticles. Such methods include forming a first layer on a substrate that comprises an axial nanoparticle, forming a second layer on the substrate that comprises an axial nanoparticle, where the first and second layers are aligned to respective first and second orientations. The disclosure also provides for multilayer materials having a first layer including a first polyelectrolyte and a first axial geometry nanoparticle which is substantially aligned along a first orientation. The multilayer material also includes a second layer including a second polyelectrolyte and a second axial geometry nanoparticle species having axial geometry, where the second nanoparticle species is substantially aligned along a second orientation which is distinct from the first orientation.

International Classification:

C07C 5/27

Abstract:

An changeable lead-lag configuration of two isomerization reactors can be used to achieve continuous isomerization operations in an aromatics production complex, even if the isomerization catalyst deactivates over time to require catalyst regeneration and/or replacement. The configuration can be particularly advantageous for two liquid phase isomerization reactors, especially those operated under a high WHSV≥5 hourwhere the isomerization catalyst can deactivate at a high rate.

International Classification:

C07C 5/27
B01J 29/42

Abstract:

A liquid phase isomerization process comprising cofeeding molecular hydrogen at a feeding rate ≥100 ppm by weight can effectively convert a C8 aromatic hydrocarbon isomerization feed in the presence of an isomerization catalyst with a very low deactivation rate of the catalyst, even at high WHSV ≥5 hour.

Abstract:

Catalyst compositions to perform selective alkyl-demethylation of C2+-hydrocarbyl-substituted aromatic hydrocarbon may exhibit a hydrogen chemisorption of at least 15% and comprise an oxide support material selected from the group consisting of an alkaline earth metal oxide, silica, a composite of an alkaline earth metal oxide and AlO, a composite of ZnO and AlO, a lanthanide oxide, a composite of a lanthanide oxide and AlO, and combinations and mixtures of two or more thereof; and a transition metal element dispersed upon the oxide support material. Alkyl-demethylation processes of a C6+ aromatic hydrocarbon-containing stream comprising C2+-hydrocarbyl-substituted aromatic hydrocarbons may comprise contacting the catalyst compositions in an alkyl-demethylation zone under alkyl-demethylation conditions to form an alkyl-demethylated aromatic hydrocarbon as an effluent exiting the alkyl-demethylation zone.

Abstract:

Methods are provided for activation of catalysts comprising low amounts of a hydrogenation metal, such as low amounts of a Group 8-10 noble metal. The amount of hydrogenation metal on the catalyst can correspond to 0.5 wt % or less (with respect to the weight of the catalyst), or 0.1 wt % or less, or 0.05 wt % or less. Prior to loading a catalyst into a reactor, the corresponding catalyst precursor can be first activated in a hydrogen-containing atmosphere containing 1.0 vppm of CO or less. The thus first-activated catalyst can be transferred to a reactor with optional exposure to oxygen during the transfer, where it can be further activated using a hydrogen-containing atmosphere containing 3.0 vppm of CO or higher, to yield a twice-activated catalyst with high performance. The catalyst can be advantageously a transalkylation catalyst or an isomerization catalyst useful for converting aromatic hydrocarbons.

Abstract:

A method for making catalyst materials is disclosed in which active metal ingredients of the final catalyst are added to a mixture for extruding the catalyst material that includes a binder, one or more precursors of one or more base metals and/or one or more noble metals, and a crystal of a zeolite. The extruded catalyst material is then pre-calcined and ion-exchanged and then a final calcining step is applied. The catalyst materials made by such a method are also disclosed as is a method for treating a hydrocarbon stream using the catalysts.
