Patent number: 8894845Abstract: Hydrocarbon feedstreams are desulfurized using an alkali metal reagent, optionally in the presence of hydrogen. Improved control over reaction conditions can be achieved in part by controlling the particle size of the alkali metal salt and by using multiple desulfurization reactors. The processes herein allow a simple and effective method for removing the majority of coke formed in the alkali metal reagent reactions with the hydrocarbon feedstreams. This makes it cost effective to run such processes at higher severities (which result in higher coke production) thereby resulting in increased amounts of valuable converted hydrocarbon product yields. The process improvements herein may also be used to increase total throughput through a unit due to the ability to effectively manage higher coke content in the reaction products.Type: GrantFiled: December 4, 2012Date of Patent: November 25, 2014Assignee: ExxonMobil Research and Engineering CompanyInventors: Walter David Vann, Daniel Paul Leta, Jonathan Martin McConnachie, Richard Alan Demmin, Douglas Wayne Hissong, William C.

Patent number: 8613852Abstract: Self-compatible heavy oil streams are produced from converted and/or desulfurized fractions. In a preferred embodiment, an incompatibility stream is added to the converted and/or desulfurized stream to reduce the solubility number of the stream. After using a water wash to remove incompatible material, a lighter fraction is removed from the stream to increase the solubility number.Type: GrantFiled: December 14, 2010Date of Patent: December 24, 2013Assignee: ExxonMobil Research and Engineering CompanyInventors: Daniel P.
