Patent number: 10053639Abstract: 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.Type: GrantFiled: October 6, 2014Date of Patent: August 21, 2018Assignee: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: Stuart S. Shih, Xiaochun Xu, William J. Novak, Carlos N. Lopez, Timothy Lee Hilbert, Stephen John McCarthy

Patent number: 10017705Abstract: This invention relates to a process involving hydrocracking and dewaxing of a feedstream in which a converted fraction can correspond to a majority of the product from the reaction system, while an unconverted fraction can exhibit improved properties. In this hydrocracking process, it can be advantageous for the yield of unconverted fraction for gasoline fuel application to be controlled to maintain desirable cold flow properties for the unconverted fraction. Catalysts and conditions can be chosen to assist in attaining, or to optimize, desirable product yields and/or properties.Type: GrantFiled: October 21, 2015Date of Patent: July 10, 2018Assignee: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: Richard Charles Dougherty, William J.

Patent number: 9365430Abstract: This disclosure relates to a novel method of making and recovering M41S family molecular sieve materials using synthesis mixtures having high solids-content and without a purification step. The solids-content, for example, is in a range from about 20 wt. % to 50 wt. %. The method also includes the step of mixing at least a portion of the M41S made with another material to form a composition, wherein the amount of said material to be mixed with said M41S product is such that said composition having less than 10 wt. % free fluid. The material mixed with the M41S made includes metal oxides, metal nitrides, metal carbides and mixtures thereof, as well as absorptive material capable of absorbing mother liquor and selected from the group consisting of carbon silica, alumina, titania, zirconia and mixtures thereof. The amount of the wastewater generated by this novel method is reduced by at least 50% to as much as 100% as comparing with conventional method of making M41S materials.Type: GrantFiled: July 30, 2008Date of Patent: June 14, 2016Assignee: ExxonMobil Chemical Patents Inc.Inventors: Wenyih Frank Lai, Robert Ellis Kay, Stephen John McCarthy
