Adsorption and stripping of ethanol from aqueous solution using sepabeads207 adsorbent

There is a problem of increasing of CO2 and CO in environment from the use of fossil fuel. Ethanol is a good alternative fuel or additive to gasoline to improve octane number, using ethanol will decrease CO and CO2 emissions. For these reasons, production of ethanol by fermentation is a promising so...
