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: Methods are provided for modifying hydrogenation catalysts having silica supports (or other non-alumina supports) with additional alumina, and using such catalysts to achieve unexpectedly superior hydrogenation of feedstocks. The modified hydrogenation catalysts can have a relatively low cracking activity while providing an increased activity for hydrogenation.

Abstract: Methods are provided for dewaxing distillate feeds using a dewaxing catalyst with improved aromatic saturation activity. The dewaxing can be performed using a catalyst including a zeolitic molecular sieve with a beneficial ratio of zeolitic molecular sieve to binder and/or using a catalyst including a zeolitic molecular sieve with a reduced ratio of silica to alumina.

Abstract: Systems and methods are provided for catalytic hydroprocessing to form lubricant base oils. The methods can include performing high pressure hydrofinishing after fractionating the hydrotreated and/or hydrocracked and/or dewaxed effluent. Performing hydrofinishing after fractionation can allow the high hydrogen pressure for hydrofinishing to be used on one or more lubricant base oil fractions that are desirable for high pressure hydrofinishing. This can allow for improved aromatic saturation of a lubricant base oil product while reducing or minimizing the hydrogen consumption. The high pressure hydrofinishing can be performed at a hydrogen partial pressure of at least about 2500 psig (˜17.2 Mpa), or at least about 2600 psig (˜18.0 Mpa), or at least about 3000 psig (˜20.6 MPa). The high pressure hydrofinishing can allow for formation of a lubricant base oil product with a reduced or minimized aromatics content, a reduced or minimized 3-ring aromatics content, or a combination thereof.

Abstract: Base stocks having Group III/III+ characteristics are prepared from certain advantageous crude oils via simplified process configurations and/or under less severe process conditions. Crude oils comprising a vacuum gas oil (VGO) fraction having a ratio of a sum of paraffin content plus 1-Ring species content to multi-ring species content that is greater than or equal to about 1.5 are advantageous in this context. Other parameters such as API gravity and crude compositional ranges may also be considered for identifying advantageous crudes. In some instances, advantageous crudes are processed into Group III base stocks via a process configuration in which the crude oil is directly supplied to a hydroprocessing unit.

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.
