Publication number: 20240166960Abstract: A method for producing renewable arctic diesel is provided herein. The method includes contacting a bio-derived feedstock with a hydrotreatment catalyst under effective hydrotreatment conditions to produce a hydrotreated feedstock and separating the hydrotreated feedstock into gas phase products and liquid phase products. The liquid phase products include an oxygen content of less than 0.4 wt % but greater than 10 ppm. The method also includes contacting the liquid phase products with a ZSM-48-based isomerization/dewaxing catalyst under effective isomerization/dewaxing conditions to produce an isomerized product stream including a change in cloud point (?CP) of 50 degrees ° C. or more. The method further includes separating the isomerized product stream into gas phase products and liquid phase products, as well as fractionating the liquid phase products to produce renewable naphtha and renewable arctic diesel with a cloud point of ?20° C. or less and a yield of 80 wt % or more.Type: ApplicationFiled: February 9, 2021Publication date: May 23, 2024Inventors: Samuel J.

Patent number: 11981870Abstract: Systems and methods are provided for processing a bio-derived feedstock in a commercial scale reactor to form renewable distillate boiling range fractions while managing the heat release. The management of the heat release is achieved in part by introducing 1.0 vol % or more of CO into at least a portion of the reaction environment for hydroprocessing of the bio-derived feedstock. The 1.0 vol % or more of CO can selectively reduce the activity of hydrotreating catalyst for olefin saturation.Type: GrantFiled: November 2, 2021Date of Patent: May 14, 2024Assignee: ExxonMobile Technology and Engineering CompanyInventors: Xiaochun Xu, Shifang Luo, Samuel J.

Patent number: 11767477Abstract: Systems and methods are provided for partial upgrading of heavy hydrocarbon feeds to meet transport specifications, such as pipeline transport specifications. The systems and methods can allow for one or more types of improvement in heavy hydrocarbon processing prior to transport. In some aspects, the systems and methods can produce a partially upgraded heavy hydrocarbon product that satisfies one or more transport specifications while incorporating an increased amount of vacuum gas oil and a reduced amount of pitch into the partially upgraded heavy hydrocarbon product. In other aspects, the systems and methods can allow for increased incorporation of hydrocarbons into the fraction upgraded for transport, thereby reducing or minimizing the amount of hydrocarbons requiring an alternative method of disposal or transport.Type: GrantFiled: August 14, 2020Date of Patent: September 26, 2023Assignee: EXXONMOBIL TECHNOLOGY AND ENGINEERING COMPANYInventors: Eric B. Shen, Anjaneya S Kovvali, Aruna Ramkrishnan, Arun K. Sharma, Samuel J. Cady, Stephen H. Brown, Rustom M. Billimoria, Brenda A. Raich, Bryan A. Patel, Phillip K. Schoch, John Della Mora

Publication number: 20220315844Abstract: Systems and methods are provided for performing slurry hydroconversion of feeds that include substantial amounts of 1050° F+ (566° C+) components. The productivity of the slurry hydroconversion reaction is improved by recycling slurry hydroconversion pitch or bottoms back to the slurry hydroprocessing reaction system. The mass flow rate of the recycle stream can correspond to 50% or more of the mass flow rate of the fresh feed to the reaction system, and the recycle stream can include more than 50 wt % of 566° C+ components. It has been discovered that using a substantial recycle stream composed of a majority of unconverted 566° C+ bottoms can increase the productivity of the slurry hydroprocessing reaction system when operating at a net conversion relative to 524° C (975° F) of less than 90 wt %.Type: ApplicationFiled: August 14, 2020Publication date: October 6, 2022Applicant: EXXONMOBIL TECHNOLOGY AND ENGINEERING COMPANYInventors: Samuel J.
