Publication number: 20110315596Abstract: 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: June 27, 2011Publication date: December 29, 2011Applicant: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: Krista Marie Prentice, Michel Daage, Ajit Bhaskar Dandekar, Christopher Gordon Oliveri, Rohit Vijay, Stephen J.

Patent number: 8070936Abstract: Contact of a crude feed with one or more catalysts containing a transition metal sulfide produces a total product that includes a crude product. The crude feed has a residue content of at least 0.2 grams of residue per gram of crude feed. The crude product is a liquid mixture at 25° C. and 0.101 MPa. One or more properties of the crude product may be changed by at least 10% relative to the respective properties of the crude feed. In some embodiments, gas is produced during contact with one or more catalysts and the crude feed.Type: GrantFiled: January 27, 2009Date of Patent: December 6, 2011Assignee: Shell Oil CompanyInventors: Scott Lee Wellington, Thomas Fairchild Brownscombe, Stanley Nemec Milam

Publication number: 20110259793Abstract: A diesel fuel product with beneficial cold flow properties can be produced. A suitable feedstock for forming a diesel boiling range product can be hydrotreated to have a sulfur content of at least about 100 wppm and then dewaxed. This two stage process can allow for production of an arctic or winter diesel without use of high pressures. Optionally, a divided wall column fractionator can be used to allow a single separation stage to handle the effluent from both the hydroprocessing and the dewaxing stages.Type: ApplicationFiled: April 23, 2010Publication date: October 27, 2011Applicant: ExxonMobil Research and Engineering CompanyInventors: Benjamin S.

Publication number: 20110253595Abstract: A whole crude oil desulfurization system and process includes a combination of an adsorption zone and a hydroprocessing zone. This combined process and system reduces the requisite throughput for the hydroprocessing unit, conventionally a very costly and process both in terms of energy expenditures and catalyst depletion. By first contacting the whole crude oil feedstock with an adsorbent for the sulfur-containing compounds, the adsorption effluent having a relatively lower sulfur content can be collected and provided to refiners without further treatment. The adsorbates, including adsorbed organosulfur compounds, are solvent desorbed resulting in a stream containing high levels of organosulfur compounds and a solvent. Following recovery of the solvent, the volume of the sulfur-containing feedstream that remains to be desulfurized in the hydroprocessing zone is substantially less than the original amount of whole crude oil feedstock.Type: ApplicationFiled: April 20, 2011Publication date: October 20, 2011Inventors: Esam Zaki HAMAD, Yuguo X Wang

Publication number: 20110240521Abstract: A system and method for producing fuels and lubricant basestocks from gas oil boiling range feeds is provided. Desulfurization and conversion stages are used to form fuel and lubricant products. The product from a desulfurization stage can be fractionated, and a portion of the fractionated bottoms can be used as an input feed for a conversion or hydrocracking stage. The configuration can advantageously allow for reduced amounts of catalyst in the conversion stage.Type: ApplicationFiled: March 31, 2011Publication date: October 6, 2011Applicant: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventor: Stuart S.
