UPGRADING OF SUGAR CANE BAGASSE BY THERMAL PROCESSES. 8. DIRECT LIQUEFACTION WITH N-ALCOHOLS

摘要

The liquefaction of sugar cane bagasse has been an important approach to produce liquid fuels and chemical feedstocks from biomass. In the present work a process has been investigated using a series of n-alcohols such as methanol, ethanol, propanol, butanol and pentanol as the conversion media. The liquefaction studies were made in an autoclave containing the bagasse and the solvent, pressurized with hydrogen (～70 bar) and heated to 370℃ for 60 minutes. The products were fractionated by preparative liquid chromatography in order to study the group-type distribution. The results obtained from liquefaction of sugar cane bagasse by ethanol suggests that this could be a good option as an alternative fuel source.
