  • Patent number: 8779209
    Abstract: The present invention provided a method for salting-out extraction of acetone and butanol from a fermentation broth, characterized in that one type, or two or more types of salts and one type, or two or more types of extractants are added to an acetone-butanol-ethanol (ABE) fermentation broth, in which the salt saturation achieves 10%˜100%; and the volume ratio of the fermentation broth containing salts to the extractants is 1:0.1˜1:5. The mixture is allowed to stand until phase separation is formed. The top phase is a solvent phase or extraction phase enriched with acetone and butanol whereas the bottom phase is a salt-enriched phase or raffinate phase. This method involves many advantages, such as the simplified operation procedure, accelerated separation process and low separation cost, and therefore becomes a promising method of separating acetone and butanol in industrial application.

  • Patent number: 8758616
    Abstract: The invention, belongs to the field of wastewater treatment technology, is a two-phase anaerobic reactor enhanced by addition of zero valent iron (ZVI). In the reactor, 2˜4 ZVI-filling layers are settled in the middle of the anaerobic hydrolysis-acidification tank, the effluent of which is fed into the rear anaerobic methanogenic tank. The degradation of organics is effectively enhanced in the anaerobic hydrolysis-acidification tank with dosing of ZVI, which may produce more acetic acid that is a desired substrate for the subsequent methanogenesis. Meanwhile, the acidic environment of the hydrolysis-acidification tank is helpful for the dissolution of ZVI to maintain its activity. The reactor is reasonably designed with high performance and strong shock resistance in anaerobic treatment of various wastewaters. Tests in lab-scale showed that hydrolysis-acidification and methanogenesis in this combined system were significantly improved compared with a reference reactor without addition of ZVI.
