Kinetics of levoglucosan and formaldehyde formation during cellulose pyrolysis process

► Kinetics study on levoglucosan and formaldehyde formation in cellulose pyrolysis. ► One pathway for formation of levoglucosan and two for formaldehyde. ► Arrhenius equations for every elementary reaction and every pathway are obtained. ► The Path3 is a more possible pathway for the formation of formaldehyde.
