Abstract: Methods are provided for forming noble metal catalysts comprising both platinum and a second Group VIII metal, such as palladium, with improved aromatic saturation activity. Instead of impregnating a catalyst with both platinum and another Group VIII metal at the same time, a sequential impregnation can be used, with the Group VIII metal being impregnated prior to platinum. It has been discovered that by forming a Group VIII metal-impregnated catalyst first, and then impregnating with platinum, the distribution of platinum throughout the catalyst can be improved. The improved distribution of platinum can result in a catalyst with enhanced aromatic saturation activity relative to a catalyst with a similar composition formed by simultaneous impregnation.

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.

Abstract: Systems and methods are provided for modifying the composition of the conversion catalyst in a reactor for oxygenate conversion during conversion of an oxygenate feed to allow for adjustment of the slate of conversion products. The modification of the conversion catalyst can be performed by introducing a substantial portion (relative to the amount of catalyst inventory in the reaction system) of make-up catalyst having a distinct composition relative to the conversion catalyst in the reaction system. Introducing the distinct composition of make-up catalyst can modify the composition of the conversion catalyst in the reactor to allow for changes in the resulting product slate. By introducing the distinct catalyst composition, the conversion catalyst in the reactor can correspond to a different composition of catalyst than the overall average catalyst composition within the catalyst inventory in the reaction system.

Abstract: Systems and methods are provided for activation of noble metal catalysts that are supported on siliceous supports. The activation method can include limiting the amount of water vapor pressure and/or the time of exposure to the water vapor pressure during heating of the catalyst at temperatures of 50° C. or less. This can be achieved by introducing heated gas into multiple reactors of a multi-reactor system at the same time. A suitable system for introducing heated gas into multiple reactors can correspond to a system with multiple heated hydrogen lines for delivery of heated hydrogen to a plurality of reactors within a multi-reactor system.

Abstract: Methods are provided for using a molecular sieve catalyst for dewaxing formed using a synthesis mixture comprising a morphology modifier. The catalyst may be used, for example, for production of a lubricant base stock. For example, ZSM-48 crystals formed using the morphology modifier (and/or formulated catalysts made using such crystals) can have an increased activity and/or can provide an improved yield during catalytic dewaxing of lubricant base stocks.
