    Abstract: The hydrotreating of petroleum feedstock is improved by using a layered transition metal catalyst, a mixture of such catalysts or a stocked bed of transition metal catalysts that has a selected ratio of edge to rim sites sufficient to provide a product having a predetermined sulfur and nitrogen content.In another aspect of the present invention, there is provided a method for selecting a transition metal catalyst system for use in hydrotreating nitrogen and sulfur containing feedstocks to provide a hydrotreated product having a predetermined nitrogen and sulfur content and at a predetermined reaction residence time, which method comprises: selecting the amount of sulfur and nitrogen to be removed from a given feedstock by hydrotreating to obtain a product having a predetermined nitrogen and sulfur content; determining the variation in the reaction kinetics for sulfur and nitrogen removal of the given feedstock by hydrotreating with a transition metal catalyst of varying edge to rim ratios; selecting, for a predetermined reaction residence time, that ratio from the varying edge to rim ratios of the transition metal catalyst that provides the requisite sulfur and nitrogen removal to provide the product of predetermined sulfur and nitrogen content.

    Abstract: Systems and methods are provided for performing field enhanced separations on a feed, such as a petroleum feed, a refinery feed, or another type of hydrocarbonaceous feed. The system can allow for increased throughput of feed per volume of the separation device or system while performing a desired amount of field enhanced separation. The field enhanced separation can include separation by thermal diffusion, optionally enhanced by the presence of an electric field in the channel for performing the separation by thermal diffusion.

    Abstract: Methods are provided for processing glycerides to form lubricant boiling range molecules in a single reactor and/or a single reaction zone. The glycerides are exposed to catalysts that are stable under the conditions present in the reaction zones during conversion of glycerides to fatty ketones via a coupling reaction in the presence of a first catalyst, and the subsequent deoxygenation and isomerization of the ketones in the presence of a second dewaxing catalyst. The glyceride-containing feedstock can further include free fatty acids or fatty acid derivatives that can also be used for formation of ketones and subsequent deoxygenation and isomerization. In some configuration, the processing can occur in a single reaction zone containing mixed beds of the first and second catalyst. Such configurations can be used to control the ratio of diesel boiling range molecules versus lubricant boiling range molecules generated by the methods.
