Much attention has been placed on finding efficient processes for the production of ethanol and other biofuels. One area that shows promise is the conversion of synthesis gas (syngas) to ethanol and hydrogen by both thermochemical and microbiological methods. Two promising methods for creating syngas are the gasification of plant biomass and the pyrolysis of carbonbased waste products. Overall ...
