Abstract
The present invention relates to devices and methods for selectively removing contaminants from a crude product mixture. In an embodiment the invention includes a method for removing organic acids from a crude product mixture including contacting the crude product mixture with a metal oxide substrate, wherein free organic acids in the crude product mixture bind to the metal oxide substrate, thereby removing free organic acids and forming a refined product mixture; separating the refined product mixture from the metal oxide substrate; and removing the organic acids bound to the metal oxide substrate by contacting the metal oxide substrate with an alkyl ester composition at a temperature of greater than about 100 degrees Celsius. Other embodiments are also described herein.
