Study of the Experimental Conditions of the Co

Some studies using rice husk in the pyrolysis process have been performed using fast pyrolysis (Yang et al 2014 Heo et al 2010 Zheng 2007) However these studies showed that the bio-oils produced from rice husk pyrolysis presented undesirable properties such as chemical instability high content of water solids ashes and oxygenated compounds which prevent its direct use in thermal
