Extraction of Bio-Butanol using Supercritical Carbon Dioxide
PubblicoRenewable biofuels such as butanol are being researched due to the depletion of fossil fuels. Researchers at MIT are genetically modifying B. Megaterium, a bacteria that survives at high pressure in anaerobic conditions, to produce bio-butanol. Butanol is potentially a great alternative for the ethanol dominated biofuel market since it is more energy dense and less flammable than ethanol. At WPI we are operating a supercritical carbon dioxide extraction system compatible with the organism. The system results show a slight increase in extraction rate when changing initial butanol concentrations from 1 to 3 wt.% but no change when increasing the pressure from 1500 to 2000 PSI. Experimental and theoretical models were created to predict extraction rates and overall mass transfer coefficients.
