Polyhydroxyalkanoate (PHA) that contains a pyrogen such as endotoxin due to a process of producing the PHA is treated to remove the pyrogen by a process that does not affect the inherent chemical and physical properties of the PHA to obtain a biocompatible PHA. PHA produced by fermentation with a Gr ...

Alfred G Wheldon: Apparatus for removing water from ethanol. The Distillers Company, Sughrue Mion Zinn Macpeak and Seas, June 27, 1989: US04842693 (108 worldwide citation)

A method and apparatus for removing water from a liquid mixture of water and ethanol contacts it with liquid carbon dioxide so that the ethanol is preferentially transferred into solution, dries the solution using an adsorbent, and then recovers dry ethanol by distilling off the carbon dioxide. This ...

Shcreck David James, Balmer Norman Louis: Integrated facility for producing alcohol using homoacidogenic fermentation. Best Energies, Shcreck David James, Balmer Norman Louis, KOTTIS Nick C, January 15, 2009: WO/2009/009322 (108 worldwide citation)

Esters are hydro genated to provide product alcohols such as ethanol. In one aspect, the hydrogenation is conducted to substantially completely react the hydrogen and provide a hydrogenation product containing product alcohol and unreacted ester which is recycled. In another aspect, hydrogen for the ...
