Publication number: 20160145511Abstract: Methods are provided for hydroprocessing a feed (such as hydrotreating, hydrocracking, or hydrofining a feed) to generate a product with a reduced or minimized aromatics content relative to the severity of the hydroprocessing conditions. In some types of hydroprocessing applications, it can be desirable to select the severity of hydroprocessing conditions to achieve a desired level of removal for sulfur, a desired level for removal of nitrogen, and/or a desired level for increasing the viscosity index of a feed. The severity for heteroatom removal and/or viscosity index uplift can also correspond to an amount of conversion of a feed to lower boiling point products, so the lowest severity conditions suitable for achieving a product quality can be desirable. By improving the aromatics saturation during hydroprocessing, the severity of subsequent aromatics saturation processes can be reduced.Type: ApplicationFiled: November 4, 2015Publication date: May 26, 2016Applicant: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: Xiaochun Xu, Bradley R. Fingland, Keith Wilson, Doron Levin, Stuart L. Soled, Sabato Miseo, Joseph E. Baumgartner, Ajit B. Dandekar

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: 9221725Abstract: Methods are provided for processing glycerides to form lubricant boiling range molecules in a single reactor and/or a single reaction zone. The glycerides are exposed to catalysts that are stable under the conditions present in the reaction zones during conversion of glycerides to fatty ketones via a coupling reaction in the presence of a first catalyst, and the subsequent deoxygenation and isomerization of the ketones in the presence of a second dewaxing catalyst. The glyceride-containing feedstock can further include free fatty acids or fatty acid derivatives that can also be used for formation of ketones and subsequent deoxygenation and isomerization. In some configuration, the processing can occur in a single reaction zone containing mixed beds of the first and second catalyst. Such configurations can be used to control the ratio of diesel boiling range molecules versus lubricant boiling range molecules generated by the methods.Type: GrantFiled: June 14, 2013Date of Patent: December 29, 2015Assignee: ExxonMobil Research and Engineering CompanyInventors: Virginia M. Roberts, Michel Daage, Paul D. Oldenburg, Suzzy C. Ho, Kun Wang, Bradley R. Fingland

Publication number: 20150218466Abstract: An integrated process for producing naphtha fuel, diesel fuel and/or lubricant base oils from feedstocks under sour conditions is provided. The ability to process feedstocks under higher sulfur and/or nitrogen 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. The integrated process includes an initial dewaxing of a feed under sour conditions, optional hydrocracking of the dewaxed feed, and a separation to form a first diesel product and a bottoms fraction. The bottoms fraction is then exposed to additional hydrocracking and dewaxing to form a second diesel product and optionally a lubricant base oil product. Alternatively, a feedstock can be hydrotreated, fractionated, dewaxed, and then hydrocracked to form a diesel fuel and a dewaxed, hydrocracked bottoms fraction that is optionally suitable for use as a lubricant base oil.Type: ApplicationFiled: February 11, 2015Publication date: August 6, 2015Applicant: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: Krista M. Prentice, Michel Daage, Ajit B. Dandekar, Christopher G. Oliveri, Rohit Vijay, Stephen J. McCarthy, Wenyih F. Lai, Bradley R. Fingland

Publication number: 20150210932Abstract: Feeds containing triglycerides are processed to produce a diesel fuel product and propylene. The diesel product and propylene are generated by deoxygenating the triglyceride-containing feed using processing conditions that enhance preservation of olefins that are present in the triglycerides. The triglyceride-containing feed is processed in the presence of a catalyst containing a Group VI metal and a Group VIII non-noble metal and in the presence of CO.Type: ApplicationFiled: December 17, 2014Publication date: July 30, 2015Applicant: ExxonMobil Research and Engineering CompanyInventors: Bradley R.

Publication number: 20140179976Abstract: Methods are provided herein for co-processing of biocomponent feeds as well processing of mineral feeds in a reaction system at hydrogen partial pressures of about 500 psig (3.4 MPag) or less. The methods include using stacked beds of both CoMo and NiMo catalysts. The stacked catalyst beds provided unexpectedly high catalyst activity as the input feed to a reaction system was switched between a mineral feed and a feed containing both mineral and biocomponent portions. Additionally, use of stacked catalyst beds can allow for maintenance of the activity for the catalyst system in a reaction system while still achieving a desired activity for both types of feeds.Type: ApplicationFiled: December 5, 2013Publication date: June 26, 2014Applicant: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: Joseph E.

Publication number: 20130338414Abstract: This invention relates to a method for hydroprocessing feedstreams containing both sulfur-containing mineral oils and biomass-derived feedstocks in a single reactor configuration. The process produces a desulfurized, deoxygenated and dewaxed hydrocarbon product having reduced oxygen content, increased iso-paraffin content, low n-paraffin content, and good cold flow properties. In preferred embodiments, the processes herein utilize water tolerant hydrodewaxing catalysts in order to prevent deactivation and/or catalyst loss due to water produced during the deoxygenation reactions in the biomass components.Type: ApplicationFiled: May 31, 2013Publication date: December 19, 2013Applicant: ExxonMobil Research and Engineering CompanyInventors: Bradley R.
