The master plan was and remains to use wood chips, corn stover and non-food crops as the feedstocks for this fuel.
"Half the improvement we make over the next 10 to 15 years will come from improving the feedstocks," said Gerald A. Tuskan, a biofuel expert in the department, referring to the crops fed into the ethanol factories.
But the feedstocks have something in common: they are derived from plants and trees, but not from food crops like corn kernels, which are the basis of most of the biofuel currently made in the United States.
The feedstocks will be specific to the region where the refineries were built — in some places, the nonfood parts of the corn plant, and in others, algae or switchgrass, he said.
The feedstocks used in this study are lingo-cellulosic biomass.
We observed only punctual differences between the feedstocks regarding the contaminants.
On the other hand, hemicellulose content in the feedstocks was calculated using the standard method [43].
Comparing the feedstocks, in molasses, the residual sugar content was observed to be lower.
The composition and lower heating value (LHV) of the feedstocks used are presented in Table 2.
The Feedstocks and Energy segment consists the businesses, including Chlor-Alkali/Chlor-Vinyl; Energy; Ethylene Oxide/Ethylene Glycol; and Hydrocarbons.
The proposed superstructure explicitly shows process configurations for the feedstocks in the uncertainty set.
