Characteristics of bio-oil, bio-char production from lignocellulosic biomass under slow pyrolysis system

Abstract

Pyrolysis is a thermochemical conversion technology to produce bio-char, bio-oil and bio-gas through the thermal decomposition of biomass under anoxic conditions. The aim of this study is investigated producing the bio-oil, bio-char, and non-condensable gas from lignocellulosic biomass via slow pyrolysis at different temperatures. Chemical composition of bio-oil is analyzed using gas chromatography-mass spectrometry (GC/MS). Bio-char, the residue of pyrolysis, was mainlyconverted to activated carbon. Activated carbon is used for purification of wastewater and removal of air pollutants.
