Co2 from ethanol production
Ethanol is a domestically produced alternative fuel most commonly made from corn. It is also made from cellulosic feedstocks, such as crop residues and wood—though this is not as common. U.S. ethanol plants are concentrated in the Midwest because of the proximity to corn production. Plants outside the Midwest typically receive corn by rail or ...An average human exhales around 2.3 pounds of CO2 in a day. That rate increases by up to a factor of eight during heavy physical exertion and falls somewhat during periods of relaxation, such as during sleep.Ethanol production through fermentation of gas mixtures containing CO, CO2 and H2 has just started operating at commercial scale. However, quantitative schemes for understanding and predicting productivities, yields, mass transfer rates, gas flow profiles and detailed energy requirements have been lacking in literature; such are invaluable …
