Patent number: 8394255Abstract: 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, or a high pressure separation can be used to partially eliminate contaminants. The integrated process includes an initial hydrotreatment, hydrocracking, catalytic dewaxing of the hydrocracking effluent, and an option final hydrotreatment.Type: GrantFiled: December 23, 2009Date of Patent: March 12, 2013Assignee: ExxonMobil Research and Engineering CompanyInventors: Stephen J. McCarthy, Gary Paul Schleicher, Krista Marie Prentice, Michel Daage, Christopher Gordon Oliveri, Thomas Francis Degnan, José Guadalupe Santiesteban, Ajit Bhaskar Dandekar, William Joseph Novak, Wenyih F.

Patent number: 6984761Abstract: A process is disclosed for producing ?-methylstyrene, acetone, and phenol wherein the amount of ?-methylstyrene produced may be controlled by selectively converting a portion of the cumene hydroperoxide to dimethyl phenyl carbinol, the hydrated form of ?-methylstyrene. The dimethyl phenyl carbinol thus produced will lead to increased production of ?-methylstyrene upon dehydration in the acid cleavage unit of the phenol plant. By controlling the fraction of the cumene hydroperoxide reduced to dimethyl phenyl carbinol, the amount of ?-methylstyrene produced in the plant can be continuously set to meet the demand of the market for ?-methylstyrene. Also disclosed is a non-acidic catalyst for reduction of cumene hydroperoxide.Type: GrantFiled: December 16, 2002Date of Patent: January 10, 2006Assignee: ExxonMobil Chemical Patents Inc.Inventors: Doron Levin, C.
