Patent number: 9487465Abstract: The present disclosure relates to processes for the separation of at least one di-carboxylic acid compound and/or at least one mono-carboxylic acid compound from a mixture. The separation processes involve contacting the mixture with an ion exchange medium to cause at least one of the mono- and/or di-carboxylic acid compounds to be retained by the medium, eluting at least one of the mono-carboxylic acid compound or the di-carboxylic acid compound using an eluent to form an eluate, wherein the eluate is enriched in at least one of the mono-carboxylic acid compound or di-carboxylic acid relative to the concentration of such eluted acid in the mixture having contacted the medium and wherein the eluent comprises an organic acid. The process has particular utility in the production of di-carboxylic acid compounds from glucose.Type: GrantFiled: November 30, 2012Date of Patent: November 8, 2016Assignee: Rennovia Inc.Inventors: Raymond Archer, Gary M.

Patent number: 8864996Abstract: This invention relates to a process for producing a product stream with improved reduction of Conradson Carbon Residue (“CCR”) and a reduced average boiling point from a heavy hydrocarbon feedstream utilizing a high-pressure, low-energy separation process. The invention may be utilized to reduce the CCR content and reduce the average boiling point in heavy hydrocarbon feedstreams, such as whole crudes, topped crudes, synthetic crude blends, shale oils, bitumen, oil from tar sands, atmospheric resids, vacuum resids, or other heavy hydrocarbon streams. This invention also results in a process with an improved CCR separation efficiency while maintaining permeate flux rates.Type: GrantFiled: October 30, 2007Date of Patent: October 21, 2014Assignee: Exxonmobil Research and Engineering CompanyInventors: Daniel P.
