Biomass
Published in Roy L. Nersesian, Energy Economics, 2016
The agricultural feedstock of choice for ethanol is sugar, also known as glucose, the simplest form of carbohydrates. The human body can easily convert sugar to energy. White refined sugar has virtually no nutritional value, while brown sugar, a less refined state of white sugar, retains some vitamins and minerals. Molasses is the residue of the sugar refining process and is mixed with cattle feed or fermented under controlled conditions to produce rum or mixed with water for another run through the ethanol making process. Sugar causes tooth decay by metabolizing into an acid that eats away at tooth enamel and contributes to obesity, diabetes, and perhaps hyperactivity when consumed in excess. Sugar may not be a good food, but is sure a good biofuel!

Ground Canadian yellow poplar (YP), and Colombian sugarcane bagasse (SCB) from the brown sugar production industry, as well as powder samples of xylan (Sigma-Aldrich, Xylan from beechwood, X4252), cellulose (Sigma-Aldrich, C6288), and lignin (Sigma-Aldrich, lignin alkali, 471003), were used to examine torrefaction kinetics and to validate the superposition approach. Proximate analysis of the samples was conducted in a muffle furnace as per the American Society for Testing and Materials (ASTM D1762-84) standard, and the ultimate analysis was conducted in an elemental analyzer (Model EA1110). The higher heating value was determined using a bomb calorimeter (Parr 6100). The polymeric properties of YP and SCB were measured using the extractive methods described by Granados et al. [47]. The measured basic fuel properties of YP and SCB are presented in Table 1.
