Question 2: This organism was recently discovered in the rainforests of northern ________ and has the unique capability of converting cellulose into medium length hydrocarbons typically found in diesel fuel.
Question 4: An advantage of ethanol (CH3CH2OH) is that is has a higher ________ than ethanol-free gasoline available at roadside gas stations which allows an increase of an engine's compression ratio for increased thermal efficiency.
Question 5: Syngas, a mixture of ________ and hydrogen, is produced by partial combustion of biomass, that is, combustion with an amount of oxygen that is not sufficient to convert the biomass completely to carbon dioxide and water.
Question 6: Green diesel is not to be confused with ________ which is chemically quite different and processed using transesterification rather than the traditional fractional distillation used to process green diesel.
Question 9: Biologically produced ________, most commonly ethanol, and less commonly propanol and butanol, are produced by the action of microorganisms and enzymes through the fermentation of sugars or starches (easiest), or cellulose (which is more difficult).
