Studies in the Area of Fuel Research Reported from University of New Brunswick

June 27, 2014

By a News Reporter-Staff News Editor at Energy Weekly News -- New research on Fuel Research is the subject of a report. According to news originating from Fredericton, Canada, by VerticalNews correspondents, research stated, "The complicated structures of bagasse hinder the bioconversion processes for the production of bioenergy and biomaterials. In this study, an integrated process of hot-water extraction followed by high-boiling-solvent cooking (HBS, i.e., 1,4-butanediol) was demonstrated to fractionate bagasse into hemicellulose, lignin, and cellulose."

Our news journalists obtained a quote from the research from the University of New Brunswick, "The hot-water extraction resulted in the removal of hemicellulose, which facilitated the HBS cooking for the open fiber structure. As a result, 57-70% of lignin was isolated from the cooking spent liquor. Gel permeation chromatography (GPC), Fourier transform infrared spectroscopy (FTIR), P-31 and H-1 nuclear magnetic resonance (NMR), and thermogravimetry (TG) were employed for characterization of the organosolv lignin. Results showed that the organosolv lignin exhibited a chemical structure similar to enzymatic hydrolysis/mild acidolysis lignin (EMAL) but formed new phenolic OH groups (3-6-fold of EMAL). The high molecular weight and thermal stability would contribute to the potential application of lignin into value-added products."

According to the news editors, the research concluded: "The proposed processes provide an efficient approach for fractionating the three main components of bagasse, especially lignin."
