Fast pyrolysis of Guadua angustifolia-Kunth

Energy Procedia, 2017
Abstract In this work, the condensable gases of the bio-oil produced from its fast pyrolysis at 500 oC for 30 s has been analyzed by Py-GC/MS. Relatively high yields of acetic acid, phenolics and levoglucosan have been found. Levoglucosan can be used as a source for synthesizing bio-fuels and both, phenolics and levoglucosan in the production of ...
