Abstract
En 中文
Bio-oil has been produced from palm kernel shell in a fluidized bed reactor. The process conditions were optimized and the detailed characteristics of bio-oil were carried out. The higher feeding rate and higher gas flow rate attributed to higher bio-oil yield. The maximum mass fraction of biomass (57%) converted to bio-oil at 550 degrees C when 2 L min(-1) of gas and 10 g min(-1) of biomass were fed. The bio-oil produced up to 500 degrees C existed in two distinct phases, while it formed one homogeneous phase when it was produced above 500 degrees C. The higher heating value of bio-oil produced at 550 degrees C was found to be 23.48 MJ kg(-1) As GC MS data shows, the area ratio of phenol is the maximum among the area ratio of identified compounds in 550 degrees C bio-oil. The UV-Fluorescence absorption, which is the indication of aromatic content, is also the highest in 550 degrees C bio-oil. (C) 2013 Elsevier Ltd. All rights reserved.
