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

Publication number: 20050246640Abstract: A method and system for displaying files to a user by presenting several lists of files and allowing a user to view metadata about particular files. The lists may be organized according to projects, software applications, or other criteria. To help the user locate the appropriate file, metadata or file property information of one file each list is displayed in a window pane for that list. The order of the files in the list may be rearranged according to properties such as size, date of last modification, etc. To reduce the input required from a user to load files, multiple files can be selected and then loaded into related software applications.Type: ApplicationFiled: April 30, 2004Publication date: November 3, 2005Inventor: Donald Lacy
