Co2 from ethanol production.
Oct 4, 2022 · An important feature of ethanol’s carbon lifecycle is the fact that combustion emissions (i.e., when the fuel is burned in the engine) are near zero. That’s because the amount of biogenic CO 2 emitted from the tailpipe when ethanol is burned in the engine is the same amount of CO 2 that was removed from the atmosphere by corn plants at the ...
Several biofuel production pathways emit an essentially pure stream of CO2 as an inherent part of their process. Such routes include ethanol fermentation (both crop-based and cellulosic) and bio-FT. The high concentration of CO2 means that the cost of capturing the CO2 is low, since no additional purification is required apart from dehydration. Abstract.
