occurs at higher temperatures when most of thermal decomposition processes are finished. Thus, in gasification process the primary pyrolysis products, condensable and non-condensable vapours and mainly char undergo secondary reactions with gasification
tube ( Knöller et al., 2005 ). Pyrolysis efficiency for oxygen yield is 100% above 1,400 °C ( Gehre & Strauch, 2003 ; Leuenberger & Filot, 2007 ); hence the pyrolysis temperature was set to 1,450 °C until 2016 and to 1,460 °C afterwards. The pyrolysis
