Abstract: Methods are provided for dewaxing a distillate fuel boiling range feed to improve one or more cold flow properties of the distillate fuel feed, such as cloud point, where the distillate fuel feed is fractionated to produce both a jet fuel product and an arctic diesel fuel product. The decrease of cloud point is achieved by using a feedstock having a concentration of nitrogen of less than about 50 wppm and a concentration of sulfur of less than about 15 wppm. Further, the dewaxing catalyst may have a reduced content of hydrogenation metals, such as a content of Pt or Pd of from about 0.05 wt % to about 0.35 wt %. A distillate fuel feed can be dewaxed to achieve a desired cloud point differential using a reduced metals content dewaxing catalyst under the same or similar conditions to those required for a dewaxing catalyst with higher metals content.

Abstract: This invention relates to methods and processes for increasing the production of FCC (Fluid Catalytic Cracking) gasoline products, and optionally distillate products, from refinery feedstocks. In particular, the processes include hydrotreating and further hydroisomerizing a typical FCC range feedstream prior to catalytically cracking the feedstream in the FCC unit. The methods herein result in higher FCC naphtha yields and lower FCC cat bottoms yields thereby significantly increasing the overall FCC gasoline production for a given operating unit and increasing the profit margin of such FCC unit operations.

Abstract: Methods and catalysts are provided for performing dewaxing of diesel boiling range fractions, such as trim dewaxing, that allow for production of diesel boiling range fuels with improved cold flow properties at desirable yields. In some aspects, the methods can include use of dewaxing catalysts based on an MEL framework structure (ZSM-11) to provide improved dewaxing activity. This can provide sufficient dewaxing activity to achieve a desired level of improvement in cold flow properties at the lower hydrotreating temperatures that are generally desired near the start of operation of a hydrotreating reactor. In other aspects, the methods can include use of MEL dewaxing catalysts with reduced ratios of molecular sieve to binder so that trim dewaxing can be provided while maintaining a desirable yield under end-of-run hydrotreating conditions.

Abstract: Methods are provided for using a dewaxing catalyst formed using at least two structure directing agents for production of a lubricant base stock. For example, ZSM-48 crystals formed using multiple directing agents (and/or formulated catalysts made using such crystals) can have an increased activity and/or can provide an improved yield during catalytic production of lubricant base stocks. Additionally or alternately, ZSM-48 crystals formed using multiple directing agents (and/or formulated catalysts made using such crystals) can provide improved aromatic saturation during processing of a feed for lubricant base stock production.
Abstract translation: 提供了使用由至少两种结构导向剂形成的脱蜡催化剂来生产润滑剂基料的方法。 例如，使用多种导向剂（和/或使用这种晶体制成的配制催化剂）形成的ZSM-48晶体可以具有提高的活性和/或可以在润滑剂基础油料的催化生产期间提供改善的产率。 另外或可选地，使用多种导向剂（和/或使用这种晶体制成的配制催化剂）形成的ZSM-48晶体可以在处理用于润滑剂基础油料生产的原料期间提供改进的芳族饱和。

Abstract: Methods are provided for making base metal catalysts with improved activity. After forming catalyst particles based on a support comprising a zeolitic molecular sieve, the catalyst particles can be impregnated with a solution comprising a) metal salts (or other precursors) for a plurality of base metals and b) an organic dispersion agent comprising 2 to 10 carbons. The impregnated support particles can be dried to form a base metal catalyst, and then optionally sulfided to form a sulfided base metal catalyst. The resulting (sulfided) base metal catalyst can have improved activity for cloud point reduction and/or for improved activity for heteroatom removal, relative to a base metal dewaxing catalyst prepared without the use of a dispersion agent.

In some aspects, the methods can include use of dewaxing catalysts based on an MEL framework structure (ZSM-11) to provide improved dewaxing activity. In some aspects improved dewaxing is achieved operating at lower pressures and with higher amounts of organic nitrogen slip from hydrotreatment.
