Production of diesel fuel from biorenewable feedstocks with selective separation of converted oxygen
Patent number: 8865953Abstract: A process has been developed for producing diesel boiling range fuel from renewable feedstocks such as plant and animal fats and oils, the process providing for sulfur management. The process involves catalytically treating a renewable feedstock by hydrogenating and deoxygenating to provide a hydrocarbon fraction useful as a diesel boiling range fuel. The hydrocarbon fraction is isomerized to improve cold flow properties. A selective separation such as a hot high pressure hydrogen stripper is used to remove at least the carbon oxides from the first zone effluent before entering the isomerization zone, and to provide liquid recycle to the treating zone at pressure and temperature. A vapor stream is separated from the isomerization effluent and at least carbon dioxide is removed using at least one selective or flexible amine solution absorber. The resulting hydrogen-rich stream is recycled to the deoxygenation reaction zone.Type: GrantFiled: June 9, 2011Date of Patent: October 21, 2014Assignee: UOP LLCInventors: John P. Brady, Tom N.

Patent number: 8383538Abstract: One exemplary embodiment can be an apparatus for treating a hydrocarbon stream having one or more compounds with a boiling point of about 140° to about 450° C. The apparatus can include an extraction zone and a regeneration zone. The extraction zone can include at least one settler. Each settler can have a height and a length. Typically the length is greater than the height. Also, the settler can form a boot, which can be adapted to receive a feed at one end. The regeneration zone may include a regenerator for an ionic liquid. The regenerator can include a column adapted to provide a regenerated ionic liquid to the extraction zone.Type: GrantFiled: February 17, 2012Date of Patent: February 26, 2013Assignee: UOP LLCInventors: Manuela Serban, Kurt M.

Patent number: 8198492Abstract: A process has been developed for producing a diesel boiling point range product and an aviation boiling point range product from renewable feedstocks such as plant and animal oils. The process involves treating a renewable feedstock by hydrogenating and deoxygenating to provide a hydrocarbon fraction which is then isomerized and selectively cracked to form the diesel boiling point range product and the aviation boiling point range product. A portion of the diesel boiling point range product, aviation boiling point range product, naphtha product, LPG, or any combination thereof can be optionally used as a rectification agent in the selective hot high pressure hydrogen stripper to decrease the amount of product carried in the stripper overhead.Type: GrantFiled: March 12, 2009Date of Patent: June 12, 2012Assignee: UOP LLCInventors: John P.
