Patent number: 9309472Abstract: Methods are provided for improving the yield of distillate products from hydroprocessing of gas oil feedstocks, such as vacuum gas oils. It has been unexpectedly found that stripping of gases or fractionation to separate out a distillate fraction during initial hydrotreatment of a feed can provide a substantial increase in distillate yield at a desired amount of feedstock conversion. The improvement in yield of distillate products can allow a desired level of conversion to be performed on a feedstock for generating lubricating base oil products while reducing or minimizing the amount of naphtha (or lower) boiling range products. Alternatively, the improvement in yield of distillate products can correspond to an improved yield during a single pass through a reaction system, so that distillate yield is increased even though a lubricant boiling range product is not generated.Type: GrantFiled: November 14, 2014Date of Patent: April 12, 2016Assignee: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: Rohit Vijay, Ajit Bhaskar Dandekar, Michel Daage, Christopher G. Oliveri, Christine Nicole Elia, Darryl Donald Lacy, Scott J. Weigel, Bradley R. Fingland

Patent number: 8906224Abstract: Sweet and sour lubricant feeds are block and continuous processed to produce lubricant basestocks. Total liquid product yields at a desired pour point are maintained for catalytic dewaxing of both sweet and sour conditions. The desired pour point is achieved for both the sweet and sour feeds by varying the catalytic dewaxing reaction temperature as a function of sulfur content entering the reactor.Type: GrantFiled: December 22, 2010Date of Patent: December 9, 2014Assignee: Exxonmobil Research and Engineering CompanyInventors: Krista Marie Prentice, Michel Daage, Gary Paul Schleicher, Christine Nicole Elia, Stephen J.

Patent number: 8366908Abstract: An integrated process for producing lubricant base oils from feedstocks under sour conditions is provided. The ability to process feedstocks under higher sulfur conditions allows for reduced cost processing and increases the flexibility in selecting a suitable feedstock. The sour feed can be delivered to a catalytic dewaxing step without any separation of sulfur and nitrogen contaminants, or a high pressure separation can be used to partially eliminate contaminants.Type: GrantFiled: December 23, 2009Date of Patent: February 5, 2013Assignee: ExxonMobil Research and Engineering CompanyInventors: Krista Marie Prentice, Gary Paul Schleicher, Lei Zhang, Timothy Lee Hilbert, Michel A.
